saturn and Uranus are alike in that they
Answer:
The correct answer is they both have rings around them
Explanation:
Saturn and Uranus are both planets in our solar system; indeed Saturn is the sixth planet while Uranus is the seventh planet. Besides this, Saturn and Uranus are giant planets, this means they are composed of gas or similar materials and they are massive. Moreover, as giant planets these two planets have a ring system, which means around them, there are dust and other particles that orbit the planet and form rings; although, in the case of Saturn these are massive and more visible. According to this, Saturn and Uranus are alike because they both have rings around them.
Answer:
They both have rings around them.
Explanation:
The only 4 planets in our solar system that are gas giants have rings.

Photosynthesis/CR definition
Answer:
Photosynthesis is the process in which green plants and some other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Cellular Respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
3. How far can an S-wave travel in 6 minutes 40 seconds?
Answer:
1800km
Explanation:
This question will be answered using the attached S-wave graph.
The graph is plotted as time (y axis) against distance (x axis).
So, when
y = 6 minutes 40 seconds
x = 1.8 * 10³ km
So, we have:
x = 1.8 * 1000km
x = 1800km

A. Oak tree and maple tree
B. Kangaroo rat and kangaroo
C. Earthworm and freshwater eel
D. Koala and black bear
Oak tree and maple tree are most likely to occupy similar niches in different ecosystem.
What is an ecosystem?An ecosystem is defined as a system which comprises of all living organisms and physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other for requirement of energy.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

(ANSWER NEEDED NOW PLS!!) your sister claims that
the digestive system works by itself to give your body energy. She states that small branches from the stomach get food to the cells throughout your body. Do you agree with this statement? Why?
My sister is right. The stomach has structures in its branches that see to the breakdown of food materials.
The digestive system is the system in the body that takes care of the breakdown of food materials and absorption of nutrients from food. The stomach houses most of the structures in the digestive system.
When food is broken down in the stomach, It is sent to other parts of the body via the circulatory system in the body. Therefore, my sister is right.

Hormones are proteins that regulate many functions in the body, such as growth and cell differentiation. Which of the following does NOT describe a function of proteins in living organisms?
Answer Options:
Proteins store energy long term, provide lubrication, and insulate the body Proteins in the form of enzymes catalyze chemical reactions Proteins provide structures in the body, such as hair and muscles Proteins in the cell membrane help transport substances into and out of cellsAnswer:
Proteins store energy long term, provide lubrication, and insulate the bodyExplanation:
Proteins store energy long term, provide lubrication, and insulate the body - this is false, this describes the role of fats. Proteins in the form of enzymes catalyze chemical reactions - this is true, enzymes are an important class of proteins in the bodyProteins provide structures in the body, such as hair and muscles - this is true, for example our hair is made of a protein called keratin Proteins in the cell membrane help transport substances into and out of cells - this is true, proteins form important pumps and channels in the cell membranewhat is the most popular cat

Look at your model and think about the relationship between oxygen and carbon dioxide in the sealed jar. Which of these statements is true?
Plants release only carbon dioxide during photosynthesis.
Plants use oxygen during photosynthesis.
Plants and animals use oxygen during respiration.
Plants and animals release oxygen during respiration.
Answer:
Plants use oxygen during photosynthsis.
Explanation:
Oxygen and carbon dioxide in the sealed jar relationship between oxygen and carbon dioxide is that Plants and animals use oxygen in respiration, hence option c is correct.
What is respiration?Water and carbon dioxide are converted into oxygen and glucose in photosynthesis and plant uses glucose and releases oxygen as a byproduct.
Oxygen and glucose are converted to water and carbon dioxide in cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which are turned into energy.
Carbon is taken out of the atmosphere by photosynthesis and put back in by cellular respiration.
Therefore oxygen and carbon dioxide have a relationship in respiration, hence option c is correct.

Sometimes after an intense exercise routine, an individual will have sore muscles 1 to 2 days following the exercise; this is called delayed onset muscle soreness. Although not completely understood, it is believed that one cause of this is damage that occurs to the Z disks and contractile filaments in the muscles. When the body attempts to repair this damage, an inflammatory response occurs that causes soreness a couple of days after the exercise has taken place. Which of these situations would likely lead to less delayed onset muscle soreness in an individual?
a. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger
b. a mutation that would reduce the amount of lactic acid buildup in muscle tissue
c. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be weaker
d. a mutation that weakens the calcium binding ability of troponin
Answer:
The correct answer is option A. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger
Explanation:
As delayed onset muscle soreness is thought to be led by the inflammatory response of the body in order to repair damage to the Z disks and contractile filaments in muscles, due to the intense exercise.
Mutation in the Z-disk protein would strengthen the connection between Z disks and contractile filaments as it is logical that this mutation could withstand more pressure or intense exercise before damage occurs to these tissues.
How big of an advantage does a variant of a gene have to give to start becoming more common in a population?
1. Greater than 0%
2. Greater than 5%
3. Double
Answer:
The correct answer is 1. Greater than 0%. An allele to become common must have a frequency of at least 0.005%
Explanation:
A polymorphic gene has more than two alleles. The more alleles there are in a population, the more polymorphic the gene is.
In a polymorphic gene, the allelic frequency of the most common allele must be minor of 99%, while the less common allele must have an allelic frequency superior to 0.005%. If any allele does not reach this frequency in the population, it is not considered to be common. In fact, it is considered to be a rare allele.
