Decribe three level of biodiverity. Which level i mot commonly meant by biodiverity?

Answers

Answer 1

The three components of biodiversity are genetic variety, species diversity, and ecosystem diversity. The variety of species in an area is referred to as species diversity.

The diversity of habitats, communities, and all biological processes among ecosystems is implied by the term "ecosystem diversity."

The variation of inheritable traits or genes present in a group of the same species is what genetic diversity is all about. A measure of diversity within an ecological community that takes into account both species richness and the evenness of species abundances is referred to as species diversity. Diversity of an ecosystem includes both habitat and community diversity.

Science has identified about 1.7 million species that exist on Earth. It is estimated that there are many more species, particularly those of tiny organisms. These projections are still being updated by scientists. 2. Describe three biodiversity tiers.

In erik erikson's theory, adults strive for generativity to achieve a sense of _______.

Answers

Immortality is the answer.

Erikson argued that personality develops in a predetermined order through eight stages of psychosocial development from early childhood to adulthood. At each stage, a person experiences a psychosocial crisis that can have a positive or negative impact on personality development.

Erikson's theory was different from many other theories because it addressed lifelong development, including old age. Older people need to look back on their lives and feel fulfilled. Success at this stage leads to feelings of wisdom, and failure leads to regret, suffering, and despair.

There are 3 possible genotypes: NN, MN, or MM. In a group of 500 people, the frequency of genotype NN is 40%. How many individuals would you expect to have the MN genotype

Answers

235 are the Individual numbers that would expect to have the MN type of genotype.

There are two equations necessary according to Hardy-Weinberg Equilibrium:-

p + q = 1

p² + 2pq + q² = 1

Let,

NN= p

NM=2pq

MM=q

So, according to the question, the frequency of genotype NN is 40%

40% of 500 = [tex]\frac{500*40}{100} = 200[/tex] Numbers of individuals

Frequency of individuals p = [tex]\frac{Numbers of individuals}{Total populations}[/tex] = [tex]\frac{200}{400} = 0.4[/tex]

Find p² by taking the square root of p.

√(p) = √(0.4)

= 0.632

So, pp + qq = 1  

qq = 1 - pp =  1 - 0.63

q = 0.37

The allele frequencies in the population are known, now finding the frequency of heterozygous genotype.

By Multiplying 2 × p ×q  to get heterozygous genotype

2pq =  2 × 0.63 × 0.37` = 0.47

2pq = 0.47

So, 2pq × total population = 0.47 × 500 = 235, NM genotype.

Here, given-

homozygous alleles 'a' have a frequency of 0.3.

Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.

The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.

Calculation-

[tex]p + q = 1\\0.3 + q= 1\\q= 1- 0.3\\\\q= 0.7[/tex]

Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-

Immunocytochemical distribution of the cannabinoid CB1 receptor in the primate neocortex: A regional and laminar analysis

Answers

Analysis:

Delta-9-tetrahydrocannabinol (Delta9-THC) has a substantial influence on higher cognitive processes, and it has been linked to the emergence or worsening of clinical symptoms of schizophrenia.

These activities appear to be mediated through the CB1 receptor, which is the most abundant cannabinoid receptor in the brain.

However, the location of the CB1 receptor in monkey neocortical areas that influence cognitive activities remains unknown.

Using antibodies that selectively target the N- or C-terminus of the CB1 receptor, we studied the immunocytochemical localization of the CB1 receptor in the brains of macaque monkeys and humans.

In monkeys, CB1 immunoreactivity was most strong in axons and boutons. CB1-immunoreactive (IR) axons showed significant variation in density and  laminar distribution throughout neocortical areas of the monkey brain.

When compared to main sensory and motor cortices, neocortical association regions such as the prefrontal and cingulate cortices have a greater  density and a distinct laminar pattern of CB1-IR axons.

For this modeling activity, assume that your species reproduces sexually. This assumption implies that it inherits
half of its chromosomes from its mother and half from its father. Recall that in sexual reproduction, individuals
inherit homologous pairs of chromosomes-one from the father and one from the mother. This arrangement
allows for two alleles for every gene. The alleles can be dominant or recessive. You will model three traits
controlled by three gene types on homologous chromosomes. Your genes should have these patterns of
inheritance:
Trait 1: Simple dominant/recessive inheritance
Example: In pea plants, YY and Yy genotypes will yield yellow pea pods, but inherited yy will yield green pea pods.
Trait 2: Co-dominance
Co-dominance occurs when there's more than one dominant allele and they express equally.
Example: Human blood type is co-dominant. I^ (type A blood), IB (type B), and i (O blood) are controlled by A and B
dominant alleles. If a person inherits A and B alleles, they'll have AB blood. O blood is caused by two recessive
alleles.
Trait 3: Incomplete dominance
Incomplete dominance occurs when there is more than one dominant gene, but the expression of both genes

Complete dominance is the mendelian inheritance pattern, while co-dominance and incomplete dominance are non-mendelian inheritance patterns. Trait 1: Hair length. Trait 2: Hair color. Trait 3: Hair type.

What is complete dominance?

When the dominant allele completely masks the recessive allele, we talk about complete dominance.

This is the case of individuals that are heterozygous for a particular gene and express the dominant trait.

The dominant allele is hiding the expression of the recessive allele.

What is co-dominance?

Codominance refers to a non-mendelian inheritance pattern in which two alleles of the same gane are equally expressed.

There is no dominant or recessive alleles, since non of them hides the expression of the other one in heterozygous individuals.

The phenotype of a heterozygote expresses two alternative variants inherited from each homozygous parent.

Heterozygous individuals express both parental phenotypes, as it is an additive expression of their parents' genes.

What is incomplete dominance?

Refers to a non-mendelian inheritance pattern in which the heterozygous individual expresses an intermediate phenotype between the dominant and the recessive phenotypes.

Neither of the involved alleles completely dominates over the other one.

What are platelets?

Platelets are pieces of very large cells in the bone marrow called megakaryocytes. They aid in the formation of blood clots that help wounds heal and to slow or stop bleeding. It can be problematic to have platelets that are too many, too few, or aren't functioning properly.

Platelets' main job is to stop and prevent bleeding. The body sends signals to platelets that direct them to the affected location when a blood artery is damaged. Adults typically have between 150,000 and 450,000 platelets per microliter of blood, which is considered normal. Less than 150,000 platelets per microliter indicate a low platelet count. People with thrombocytopenia have low platelet levels. We can bleed heavily and bruise easily if our platelet counts are low.

Because it generates a new DNA sequence for a particular gene, the mutation is crucial in the initial stage of evolution because it results in the creation of a new allele. Through intragenic recombination, recombination can also produce a new DNA sequence (a new allele) for a particular gene.
