5. Explain the genotypes and phenotypes of skin color.

Answers

Answer 1
Human skin color is a polygenic trait, which means that multiple gene loci (with different alleles) are involved in its expression. Because of this, there is an enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues.

If the half-life of a radioactive atom is 3,500 years. How old is the substance if the parent-daughter ratio is 1:127?

Answers

Answer:

2.447 × 10⁴ years

Explanation:

Step 1: Given data

Half-life of the radioactive atom (t1/2): 3,500 yearsParent-daughter ratio ([A]/[A]₀): 1:127 (1/127)

Step 2: Calculate the rate constant

Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.

k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹

Step 3: Calculate the time elapsed (t)

For first-order kinetics, we will use the following expression.

ln ([A]/[A]₀) = -k × t

t = ln ([A]/[A]₀)/ (-k)

t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y

The autonomic nervous system works without our control. Which of the following does
cardiac muscle fall under?
involuntary or
voluntary

Answers

Answer: Involuntary.

The Autonomic nervous system is a subdivision of the Peripheral nervous system and it is in charge of the involuntary processes in the body such as blood pressure, respiration and the heart rate. As such, its effectors are under involuntary control.

The Autonomic nervous system controls the smooth and cardiac muscles in the body as well as the glands. This is where it earns its other name, the Visceral nervous system.

Deforestation of land can also lead to desertification and a loss of biodiversity.The burning of fossil fuels and the growth of animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. In turn, this drives climate change.Humans affect the quality, availability, and distribution of Earth's water through the modification of streams, lakes, and groundwater . ... The activities of humans have significantly altered the biosphere , changing or destroying natural habitats and causing the extinction of many living species.

19. Explain the following observation made by Gregory Mendel in his experiments, A cross between a
pure breed tall plant and a pure breed dwarf plant had all the first filial generation being tall.​

Answers

Answer:

The correct answer is - can be explained by the law of dominance.

Explanation:

In this experiment of Gregory John Mendel where he made a cross between a purebred tall plant and a purebred dwarf plant and in the first generation all the offspring were tall.

It can be explained by that every offspring get one allele from both parents and in purebred both alleles are either dominant or recessive and both parent plant gives one allele which makes a heterozygous condition in which the dominant allele masks the recessive allele and offspring express phenotype of the dominant parent.

Answers

Answer:

A. The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.

Explanation:

got it right on edg quiz (see pic)

hope this helps :)

All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.

What is the digestive and excretory system?

Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.

The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.

The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).

Therefore, the correct answer is a).

What is Ecological succession?

Ecological succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.

Pioneer organisms are those organisms that arrive first in any ecosystem which is bare. The pioneer species are always found to be present in the bare area. The organisms that are the last organisms to appear known as climax organisms.

Pioneer organisms modify the environment in such a way that makes the bare atmosphere a little bit improved with respect to the need of other organisms.

Therefore, the correct option for this question is D.
