Answer:
D
Explanation:
As population grows all the above factors increase expect the biodiversity of animal and plant species.
On a basic level, it is obvious that population increase and per capita income growth are related. Per capita income is simply total income divided by the population. Thus, option D is correct.
What inverse relationship to population growth?When attempting to forecast changes in population size, demographers frequently focus on four essential criteria.
The population's starting age profile (whether it is relatively young or old to begin with), migration, and fertility rates (death rates; life expectancy).
Depending on particular environmental factors, two different patterns of population expansion may manifest: In a perfect, limitless environment, an exponential growth pattern (J curve) manifests itself.
The development of a logistic growth pattern (S curve) occurs when external forces reduce the pace of growth.
Therefore, The gap between the growth rates of income and population is roughly equivalent to the growth rate of per capita income.

which parts of the monomers involved in the dimer formation
Answer:
A dimer (/ˈdaɪmər/) (di-, "two" + -mer, "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. The term homodimer is used when the two molecules are identical (e.g. A–A) and heterodimer when they are not (e.g. A–B).

The right whale is an example of
A. a species that is recovering from being endangered
B. a species that failed to adapt to changes to its environment
C. a species that is almost gone because of the excessive pollution in its habitat
D. a species that has become too populous and threatens the survival other of species
Answer: I believe it's C
Explanation: edg 2021
The correct option is C.
Why do they call it a right whale?
The right whale got its name because it was the right whale to hunt—it moved slowly and would float after being killed. A North Atlantic right whale mother and calf were spotted off the U.S. southern coast by NOAA researchers during the 2020 breeding season.
How rare is a right whale?North Atlantic right whales have been listed as endangered under the Endangered Species Act since 1970. The latest preliminary estimate suggests there are fewer than 350 remainings, with fewer than 100 breeding females. The number of new calves born in recent years has been below average.

active transport moves mineral ions into root hair cells through cell membrane proteins. Explain how protein molecules move ions across a membrane during this process. (3marks)
Explanation:
Small and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.
Nonpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients.

what is the main difference between a biome and an ecosystem
An ecosystem is quite smaller than a biome and exists within a biome.
A biome refers to a large habitat ocupied by assorted fauna and flora. Biomes are classified based on abiotic conditions such as temperature, soil types, rainfall etc. An ecosystem is a self supporting unit in which materials and energy are exchanged within the system.
The difference between a biome and an ecosystem is that a biome is a collection of different ecosystems that are found within a habitat while an ecosystem is composed of living and nonliving factors. An ecosystem is quite smaller than a biome and exists within a biome.

A student is researching the inheritance patterns of different traits in chickens. She hypothesizes that red feathers are dominant over black, and the trait for crests are dominant over non-crested. She performs a test cross to confirm her hypothesis. To produce the F1 generation, she crosses two parents-- a chicken that is homologous for traits showing red and crested and a chicken that is homologous for traits showing black and non-crested. Which ratio best represents the phenotype of the F2 generation
9:3:3:1
1:1:1:1
2:2:1:1
16:0
Answer:
9:3:3:1
Explanation:
In this inheritance pattern, the ratio that best represents the phenotype of the F2 generation is 9:3:3:1. Thus, the correct option for this question is A.
What is a Phenotype?A phenotype may be defined as the mechanism of expressing genotypes in the form of traits. In more simple words, it is also characterized as the morphology or physiology which comes due to the combination of alleles.
If a trait of red feathers is denoted by R and the trait of black feathers is denoted by r, then R > r. Similarly, a trait of crests is denoted by C and the trait of non-crested is denoted by c, then, C > c.
Now, RRCC is crossed with rrcc, the F1 offspring have the genotype RrCc with the phenotype of red feathers with crests. Now, RrCc is selfed, it produces the ratio of 9:3:3:1. This is an example of a dihybrid cross.
Therefore, in this inheritance pattern, the ratio that best represents the phenotype of the F2 generation is 9:3:3:1. Thus, the correct option for this question is A.

Answer:
Reproduction is the manufacturing of offspring. There are primary forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic statistics from each of its mother and father and is genetically unique. In asexual reproduction, one parent copies itself to shape a genetically same offspring.
