A survivorship curve reflects the relationship of survival rate with age. best curves the statement about survivorship.

Explanation:

heyy mate! hope this helped you!

A survivorship curve is a graph that shows the proportion of individuals in a population surviving at different age intervals. The correct statement is that survivorship curve describes the pattern of mortality in a population over time. The correct option is C.

What is Survivorship curve?

Survivorship curve describes the pattern of mortality in a population over time. The survivorship curve is divided into three types, i.e., Type 1, Type 2, and Type 3. Survivorship curve type 1 represents a high survival rate throughout the lifespan of the population. It shows that most individuals survive until old age, and the mortality rate increases at the end of the lifespan.

Survivorship curve type 2 shows a relatively constant rate of mortality throughout the lifespan of the population. It indicates that the probability of survival remains the same throughout life.

Survivorship curve type 3 represents high mortality rates among young individuals in a population. It shows that most individuals die young, and only a few individuals survive to adulthood.

Therefore, the correct option is C.

Answer:

Mechanoreceptors would be activated

Explanation:

The skin is a complex organ that is found covering the entire surface of the human body. The mechanoreceptors are responsible for the sense of touch, that is, the capture of pressure on the skin. They are the Meissner corpuscles and the Vater-Pacini corpuscles, which are made up of nerve endings and connective tissue, in other words, they are receptors that are stimulated by muscle contraction and pressure on the joint elements. It allows to know the position of the body and the degree of contraction of the muscles.

Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.

Explanation:

Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.

The correct fillers for the given statements are: "22" and "personality and cognitive abilities"

Chromosomes are thread-like minute structures found in the nucleus of the plant and animal cells. These are the structures that help in transferring genetic information from one generation to another. Half chromosomes come from the mother and half come from the father's reproductive cells.

Humans have 23 chromosome pairs in their cells, one out of 23 pairs is responsible for the gender of the human embryo or child.the other initial 22 pairs are responsible for providing directions for an individual's body and brain development.On the basis of studies, many scientists say that almost half of the traits of personality and cognitive activities or mental processes to learn or acquire activities are due to chromosomes.

Answer:

a. To the right

b. higher

Explanation:

From the information given:

a.

The oxygen-adsorption curve of the elevated high altitude modified the hemoglobin and this will move to the right because there is a reduced amount of oxygen available at high altitude, as well as an increase in carbon dioxide and H+ ion concentration, temperature, and all of which raise pH and shifts the curve towards the right.

b.

As there is a low relative partial pressure of oxygen at high altitude, the oxygen-binding attraction of high altitude adaptable hemoglobin is greater and higher than that of unadapted hemoglobin under pulmonary oxygen loading. This is important to optimize the oxygen concentration levels in blood circulation and blood tissues.

My argument runs like this. I’ll construe “science” as the set of tools we use to find truth about the universe, with the understanding that these truths are provisional rather than absolute. These tools include observing nature, framing and testing hypotheses, trying your hardest to prove that your hypothesis is wrong to test your confidence that it’s right, doing experiments and above all replicating your and others’ results to increase confidence in your inference.

And I’ll define religion as does philosopher Daniel Dennett: “Social systems whose participants avow belief in a supernatural agent or agents whose approval is to be sought.” Of course many religions don’t fit that definition, but the ones whose compatibility with science is touted most often – the Abrahamic faiths of Judaism, Christianity and Islam – fill the bill.

Next, realize that both religion and science rest on “truth statements” about the universe – claims about reality. The edifice of religion differs from science by additionally dealing with morality, purpose and meaning, but even those areas rest on a foundation of empirical claims. You can hardly call yourself a Christian if you don’t believe in the Resurrection of Christ, a Muslim if you don’t believe the angel Gabriel dictated the Qur’an to Muhammad, or a Mormon if you don’t believe that the angel Moroni showed Joseph Smith the golden plates that became the Book of Mormon. After all, why accept a faith’s authoritative teachings if you reject its truth claims?

Indeed, even the Bible notes this: “But if there be no resurrection of the dead, then is Christ not risen: And if Christ be not risen, then is our preaching vain, and your faith is also vain.”

Many theologians emphasize religion’s empirical foundations, agreeing with the physicist and Anglican priest John Polkinghorne:

“The question of truth is as central to [religion’s] concern as it is in science. Religious belief can guide one in life or strengthen one at the approach of death, but unless it is actually true it can do neither of these things and so would amount to no more than an illusory exercise in comforting fantasy.”
The conflict between science and faith, then, rests on the methods they use to decide what is true, and what truths result: These are conflicts of both methodology and outcome.

In contrast to the methods of science, religion adjudicates truth not empirically, but via dogma, scripture and authority – in other words, through faith, defined in Hebrews 11 as “the substance of things hoped for, the evidence of things not seen.” In science, faith without evidence is a vice, while in religion it’s a virtue. Recall what Jesus said to “doubting Thomas,” who insisted in poking his fingers into the resurrected Savior’s wounds: “Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.”


Two ways to look at the same thing, never the twain shall meet. Gabriel Lamza/Unsplash
And yet, without supporting evidence, Americans believe a number of religious claims: 74 percent of us believe in God, 68 percent in the divinity of Jesus, 68 percent in Heaven, 57 percent in the virgin birth, and 58 percent in the Devil and Hell. Why do they think these are true? Faith.

But different religions make different – and often conflicting – claims, and there’s no way to judge which claims are right. There are over 4,000 religions on this planet, and their “truths” are quite different. (Muslims and Jews, for instance, absolutely reject the Christian belief that Jesus was the son of God.) Indeed, new sects often arise when some believers reject what others see as true. Lutherans split over the truth of evolution, while Unitarians rejected other Protestants’ belief that Jesus was part of God.

And while science has had success after success in understanding the universe, the “method” of using faith has led to no proof of the divine. How many gods are there? What are their natures and moral creeds? Is there an afterlife? Why is there moral and physical evil? There is no one answer to any of these questions. All is mystery, for all rests on faith.

The “war” between science and religion, then, is a conflict about whether you have good reasons for believing what you do: whether you see faith as a vice or a virtue.

Compartmentalizing realms is irrational

So how do the faithful reconcile science and religion? Often they point to the existence of religious scientists, like NIH Director Francis Collins, or to the many religious people who accept science. But I’d argue that this is compartmentalization, not compatibility, for how can you reject the divine in your laboratory but accept that the wine you sip on Sunday is the blood of Jesus?

What is the food web?

When many food chains of an ecosystem are interconnected with each other to make a complex web-like structure is known as the Foodweb.

Lindeman gave the 10% law which means at each step of the food chain when food energy is transferred from one trophic level to the next trophic level, only about 10% of energy is passed on to the next trophic level.

Producers (100%) → Primary consumer (10%) → Secondary consumer(1%) → Tertiary consumer (0.1%).

Therefore, If producers receive 1,000kcal of energy from the sun, the energy received by the tertiary consumers in that energy pyramid is 1kcal.

It regulates voluntary activities.
It relays information to and from skin and skeletal muscles

Explanation

The somatic nervous system is part of the peripheral nervous system (part of the nervous system consisting of nerves and ganglia, and whose essential role is the transmission of information between the central nervous system - brain and spinal cord - and organs). It intervenes in the voluntary control of movements (or involuntary movements in case of reflexes, but this is different from the involuntary activities) (efferent fibers) and in the perception of external stimuli (afferent fibers).

The somatic nervous system controls the movements of skeletal muscle (which are generally voluntary) and the environmental perception, (think to the arc reflex).

The involuntary activities (proposition 1) mean automatisms like the heartbeat, respiration, secretions of hormones or sweat

I believe the answer is the last one. The average intake in 2010 was 1030 mg approximately and that, according to experts is not enough.  

The American diet is very high in sodium which is not good for your blood pressure. It was, some time ago, recommended that the average intake of Sodium should be about 2 grams. Two hamburgers will shoot that number to the moon, so now it is 4 grams. which if 2 grams was high, 4 grams is super high. Junk food prevails in America.

Fiber is true. It is low. The American Heart Association recommends 25 grams of Fiber a day. The average American takes in 15 which is only 60% of the recommended amount.

B. Low in fiber. This is incorrect. The correct answer would be HIGH in fiber, so therefore the answer is B.

Answer:

a. 80%

b. 86%

c. 60 g

d. 34.29%

Explanation:

From the given information:

The apparent nitrogen digestibility (AD) is the ratio of the difference between the consumed nitrogen and fecal nitrogen to the consumed nitrogen.

Mathematically:

[tex]AD = \dfrac{consumed \ nitrogen - fecal \ nitrogen }{consumed \ nitrogen }[/tex]

[tex]AD = \dfrac{175 -35 }{175}[/tex]

AD = 0.8

To percentage, the apparent Nitrogen digestibility = 80%

b. True Nitrogen digestibility is calculated by the formula:

[tex]=\dfrac{consumed \ nitrogen - (fecal \ nitrogen -metabolic \ fecal)}{consumed \ nitrogen}[/tex]

[tex]= \dfrac{175 -(35-10)}{175}[/tex]

[tex]= \dfrac{175 -25}{175}[/tex]

= 0.86

= 86%

c. Nitrogen Balance = consumed Nitrogen - Fecal nitrogen - total uninary

Nitrogen Balance = (175 - 35 - 80) grams

Nitrogen Balance = 60 g

d. Apparent Nitrogen Retention (ANR) is computed as follows:

[tex]ANR = \dfrac{(consumed \ nitrogen-fecal\ nitrogen - total \ uninary )}{nitrogen \consumed }\times 100\%[/tex]

[tex]ANR = \dfrac{(175-35- 80 )}{175 }\times 100\%[/tex]

[tex]ANR = \dfrac{(60 )}{175 }\times 100\%[/tex]

ANR = 34.29%
