When thinking about genotypes and phenotypes, which is the cause and which is the effect?

Answers

Answer:

A particular genotype does not necessarily guarantee a particular phenotype. Understanding what factors can change this expression is quite complex.. What is what i believe that above statement meant.

Explanation:

Error is the stochastic variation associated with a particular observation of the phenotype (and is managed by use of replication and and appropriate experimental design). The phenotype is the result not only of the average effect of the different alleles at a given locus across test units and across environments, but is impacted by the interaction between the different alleles and the environments (including genetic backgrounds) in which they are evaluated. Phenotype is not simply the sum of the genotype effect and the environment effect, as indicated in the mathematical formula that you provide.

A. logistical


B. an r-strategist


C. a K-strategist


D. density dependent

THE ANSWER IS....

Answers

Answer:

B. an r-strategist

Explanation:

R-strategist (also known as r-selected species) refers to species whose population growth is based on the maximum reproductive capacity of the individuals under optimum environmental conditions (i.e., the biotic potential). These species are well known to produce numerous offspring and they show exponential population growth. The most common features of the R-selected species are 1-high reproductive rate, 2-rapid development, 3-early reproductive age, 4-small size,  5-short life spans, 6-poor competitive ability, and 7-high mortality. Some examples of r-selected species include rabbits, mice, marine invertebrates (e.g. jellyfish), weeds, bacteria, etc.

Answer:

Thanks so much for giving the answer!

It is r-stragery though.

k-stratergy produce fewer offspring slowly- such as an elephant.

r-strategey produce offsping rapidly- such as a (nasty) fly.

6. a) In what way is the genetic code in all organisms the same? (1 point)

Answers

Answer:

they all come from the same ancestor, and all organisms have DNA made of the same molecules that form our genetic code. DNA in every organism has the bases: A,T,C,G.

Also, don't use this if it's still June 2021 and you're doing ap ex, we might have the same teacher.

All living organisms use the same genetic code. This shows that all organisms share a common evolutionary history.

What is a genetic code ?

The genetic code is the set of rules used by living cells to translate information encoded within genetic material into proteins. It is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.

The genetic code is universal. Living systems use nucleic acids and the same three-base codons to direct the synthesis of proteins from amino acids. For example, the mRNA codon UUU, codes for phenylalanine in all cells of all organisms.

a) varigated
leaves accumulates less Food than non-varigated leaves under similar condition​

Answers

Answer:

Due to less number of chlorophyll.

Explanation:

The variegated  leaves accumulates or produces less amount of food than non-variegated leaves under similar condition​ because variegated  leaves has number of chlorophyll as compared to non-variegated  leaves. Chlorophyll is a green pigment that is responsible for the photosynthesis in plants, without chlorophyll no photosynthesis occurs in the plants. The variegated  leaves has less number of chlorophyll as compared to non-variegated  leaves which leads to less production of food in variegated  leaves.

Both B and D

Answers

Answer:

D. is not very significant because it gives us little insight into human behavior.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

As a scientific concept, race is not very significant because it gives us little insight into human behavior.

This ultimately implies that, race is a scientific concept that holds no significant or absolute value since the nineteenth century.

Hence, the difference between humans shouldn't be described based on race according to the United Nations Educational, Scientific and Cultural Organization (UNESCO).

Answers

Answer:

D. Homeostasis

Explanation:

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Basically, the endocrine system contributes significantly to the state of homeostasis in the body.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

Ay, Where are they?Think not of them, thou hast thy music too,While barred clouds bloom the soft-dying day,And touch the stubble-plains with rosy hue;Then in a wailful choir the small gnats mournAmong the river sallows, borne aloftOr sinking as the light wind lives or dies;And full-grown lambs loud bleat from hilly bourn;Hedge-crickets sing; and now with treble softThe red-breast whistles from a garden-croft;And gathering swallows twitter in the skies.Question 1Part AWhat inference can be drawn from "To Autumn"?Autumn is a beautiful season, but spring is much preferred.Autumn is a peaceful and abundant season, full of natural beauty.Autumn is a sad season, and the autumn of life is equally sad.Autumn is simply a precursor to winter, and the autumn of life is a time of grief.Question 2Part BWhich evidence from the text best supports the answer in Part A?"Where are the songs of spring?
