Explain how meiosis results in UNIQUE cells.
Answers
Meiosis is a reduction division in which the number of chromosomes in the parent cells is halved to the daughter cells.
Meiosis is the process such as:
Meiosis occurs in the reproductive cells of humans. Meiosis transmits genetic information from parent to offspring. Meiosis is the characteristic feature of sexual reproduction. The male and female gamete fuse to give rise to a newly formed combination of the daughter cells.Meiosis results in the recombination of male and female gametes, which results in the independent assortment of the genes.
Thus, meiosis always results in new variations and creates genetic diversity.

You want to identify dominant /recessive relationship for skin color for a new frog species that you found in the rain forest. Assume that one autosomal gene controls skin color in this species. All of the frogs that you found for that spe- cies are bright blue or yellow. A bright blue female and bright blue male frog mate and produce all bright blue progeny. A yellow female and yellow male frog mate and produce a mix of bright blue and yellow progeny. Identify each trait (bright blue skin color and yellow skin color) as dominant or recessive. Explain your choices.
Required:
Identify the genotype for each parent in the two crosses.
Answers
Answer:
bright blue trait = recessive
yellow trait = dominant
Explanation:
let the letter B represent the gene for skin colour.
This means that the dominant gene is 'B' while the recessive gene is 'b'
A dominant gene is one that is exhibited phenotypically in the presence of both gene variants (heter0zygous state - Bb) while a recessive gene is only expressed phenotypically when it is in a h0m0zygous state (bb)
In order to find out the genotype of the parents, let us consider each cross one after the other.
1. A bright blue female and a bright blue male produce all blue progeny.
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny
From statement 2, it can be deduced that the trait for yellow colour is dominant because a cross of the parents exhibiting this trait produces bright blue offsprings too, meaning that the genetic composition of the parents contains the gene that codes for yellow colour. Since these parents show a yellow colour in a heterozygous state, then the trait for yellow colour is dominant.
Therefore, the genotypes of the parents in each case include:
1. A bright blue female and a bright blue male produce all blue progeny. (bb × bb)
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny (Bb × Bb)

How does an increase in atmospheric carbon dioxide effect the oceans?
Choose all that apply
-It causes them to dry-up and shrink in size.
-It causes sea levels to rise.
-It causes them to be more acidic.
-it causes them to be warmer.
Answers
Explanation:
Definitely global warming is correct because global warming is a slow process, a few degrees in hundreds of years. Moreover, there are multiple sources (causes) responsible for Earth warming. Though the Earth warms up very slowly (incomparably slower than heating a pot of water on the stove, where the heating source is only one), it occurs much faster than thousands of years ago.
An increase in atmospheric carbon dioxide is that the level of carbon dioxide is getting increased and the level of global warming is getting increased.
What is the pollution ?The pollution is the unwanted wastes that are coming out in the nature and the environment such that the level of increasing bad effects of air are increased.
It causes them to dry-up and shrink in size. It is because of the increased temperature that increases most importantly this condition of drying up and all. The sea level is increased when there is increase in water level due to the maximum water melting from glaciers that cause the water to increase in oceans.
Global warming is the intact reason that sounds so relevant to the situation where the condition is like that the increasing water will automatically level up other concerns as well that is because of the green house gases.

Suppose all the alleles on on the left and right chromosomes switched places but kept the same order. Would the organism be different? Why or Why not?
Answers
Answer:
No
Explanation:
The chromosome will stay the same organism.
The organism would be same in both homogenous and heterogenous chromosome . Therefore, switching the alleles won't change the organism if order is maintained.
What is chromosome and its type ?The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.
An organism is said to be homozygous if it has identical genes on both chromosomes. It is referred to as heterozygous if the organism possesses two distinct alleles of the gene.
Therefore, if the alleles switched places but the order remains same then organism will be same too in case of homologus as well as heterologus chromosome.

Most of the oxygen in the atmosphere is made by algae. Where do most of the algae live?
coastal ocean
deep ocean
ponds
lakes
Answers
Explanation: It’s important to remember that although the ocean produces at least 50 percent of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean.
This is particularly problematic when algal blooms die and the decomposition process uses oxygen faster than it can be replenished. This can create areas of extremely low oxygen concentrations, or hypoxia. These areas are often called dead zones, because the oxygen levels are too low to support most marine life.
NOAA’s National Centers for Coastal Ocean Science conducts extensive research and forecasting on algal blooms and hypoxia to lessen the harm done to the ocean ecosystem and human environment.
Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae. Hence the correct option is A.
What is Algae?Algae is defined as a member of a group of primarily aquatic photosynthetic organisms of the Protista kingdom. Algae is described as floating green matter on the surface of a pond, lake, river, still water, moist soil, stones that grow on wet surfaces. Therefore, they can synthesize their own food. They are found in water or in very moist places.
Algae play many important and beneficial roles in freshwater environments producing oxygen and consuming carbon dioxide that act as the base of the aquatic food chain, removing nutrients and pollutants from the water and stabilize sediments. Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae.
Hence the correct option is A.

Which components of the cardiac cycle (atrial systole and diastole, ventricular systole and diastole) are discernible in the pulse tracing? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Answers
Answer:
D. Heart contraction and pulse are connected with one another.
E. Atrial diastole and ventricle diastole.
Explanation:
Heart construction and pulse of an individual are connected as one can hear the pulse every time contraction of the heart is completed. Pulse can be understood by this that it represents the number of the contractions is completed by heart each time.
In the pulse tracing, there are two parts of the heart that are discernible which represents the contraction of the heart that are Atrial diastole and ventricle diastole.
The relationship between the pulse recorded in the finger and heart muscle contraction is that both are connected to each other. But, the analysis and processes are different from one another.
What is Muscle Contraction?
A process leading to shortening and/or development of tension in muscle tissues that means the thin filaments slide over the thick filaments and tension is generated between one another is called Muscle contraction.
The pulse recorded in the finger is a signal for flowing the blood throughout the body, while the process of heart muscle contraction signals for electrical conductivity. Both the functions are connected with each other and acquired by cardiac activities.
The components of the cardiac cycle that are discernible in the pulse tracing are Ventricular systole (contraction) and ventricular diastole (relaxation).
Therefore, both the pulse recorded in the finger and heart muscle contraction interconnected with one another and acquired by cardiac activity.
