Mammalian erythrocyte lacks nucleus. Why? Give reason.
Explanation:
Complete answer:
A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.

An individual always has two alleles for the same gene (one on each chromosome). Which statement is true?
a)A person's two alleles are always different
b)A person's two alleles are always the same.
C)A person's two alleles may be the same, and they may be different
Answer:
A
Explanation:
An individual always has two alleles for the same gene (one on each chromosome). The statement which is true is "a person's two alleles may be the same, and they may be different". Thus, the correct option is C.
What are alleles?An allele can be referred to as an alternative form of a gene. An allele is located at a specific position on a specific chromosome. These alleles can be passed on from the parents generation to their offspring through the process of sexual reproduction.
The presence of two identical alleles at a particular gene locus (chromosome) is referred to as a homozygous genotype. This may include two normal alleles or two alleles that have the same variant. The presence of two different alleles at a particular gene locus is referred to as a heterozygous genotype.
Therefore, the correct option is C.

HELP PLS PLS PLS Describe how commercial fishing by humans can have a negative impact on the balance of organisms in an aquatic environment.
Answer:
Aside from reducing fish stocks, unsustainable fishing practices can have other negative impacts on the marine environment. For example, some fishing techniques such as dredging and trawling can cause widespread damage to marine habitats and organisms living on the sea floor

why adaptation is important for living beings
Answer:
Adaption is needed for a living thing to strive in a system, its how they survive.
Explanation:
Adaptation is needed to survive. This includes climate, predators around it etc. For example polar bears. Polar bears adapt to their environment by growing thick coats of fur. These coats keep the bears warm.Without it they would die.
Examine the genotype for an individual who is AaBbCcDd. Predict the outcomes of meiosis and the potential gamete combinations
that could form from this individual. Select ALL that apply.
A)
50% of the gametes will be AaBbCcDd.
B)
1/16 of the gametes produced will be ABcd.
The individual could make gametes that contain ABCD.
D)
The individual could make gametes abcd half of the time.
E)
Only dominant traits will be present in the gametes from a heterozygous
individual
Answer: B,C
Explanation:
I did just did the USA test prep
The outcomes of meiosis and the potential gamete combinations that could form from the genotype for an individual who is AaBbCcDd:
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.A gamete that is formed by the meiosis, is a reproductive cell which has haploid set of chromosomes arise from the genotype, the total number of chromosome in mature organism cells.
A a simple method to calculate the number of gametes:
Count the number of heterozygous alleles i.e Aa Bb Cc and Dd which means 4.n = 4
Then, total number of gametes will be = [tex]2^{n}[/tex] or [tex]2^{4}[/tex] = 16Thus 16 in this condition
The 16 types of gametes are formed by this individual by permutation and combination are:
ABCD, AbCD, ABcD, ABCd,
ABcd, AbcD, ABCd, Abcd,
aBCD, aBCd, aBcd, aBcD,
abCD, abCd, abcd, abcD.
Thus, the correct answer is -
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.Learn more about permutation and combination:

Which of the following are density-dependent factors? (Choose all that apply)
flash floods
disease
food supply
volcanic eruptions
which of the following is density- independent factor?
flash floods
genetic diversity
food supply
water availability
Answer:
Since “DENSITY FACTORS” affect a population in the same ways as others. I will say DISEASE & FOOD SUPPLIES
The following are density-dependent factors are:
b. disease
c. food supply
Density-dependent factors:Density dependant elements can have either a positive or a negative relationship to populace size. With a positive relationship, these restricting variables increment with the size of the populace and breaking point development as populace size increments.
This includes disease, predation, and food supply.
Thus, correct options are b and c.

Jeremy is observing a cross-section of a corn stem under the microscope. He observes that there is no vascular cambium present in this stem.
Why is there no vascular cambium in corn stems?
Α.
Vascular cambium is an apical meristematic tissue that is responsible for increasing the height of the plant, which is not
observed in monocots such as corn.
B.
Vascular cambium is a lateral meristematic tissue that is responsible for thickening of the plant, which is not observed in
monocots such as corn.
C.
Vascular cambium is an apical meristematic tissue that is responsible for thickening of plant, which is not observed in
monocots such as corn.

A farmer wants to produce pigs that are larger in order to get more meat from them to profit. How could the farmer get larger pig offspring from their population of pigs on the farm? In your response, be sure to include:
Would this be sexual or asexual reproduction?
Would this be natural or artificial selection?
Explain the process of natural or artificial selection that the farmer would use.
Describe some potential downfalls (negative things) from doing this.
(Your response should be at least 4 sentences.)
PLS I NEED THIS IN LESS THEN 3 MINUTES
Answer:
This would be sexual reproduction and artificial selection.
The farmer would take the largest pigs to breed so they can both give their genes to their offspring which would then also most likely be large.
This can cause genetic mutations and diseases within the farmer's pigs.
Explanation:
Sexual reproduction because you have 2 organisms in the process of pigs reproducing.
Since the farmer is picking and choosing which animals are breeding with each other, it would be artificial selection.
How do environmental factors influence genetic traits?
a.
Environmental factors determine all genetic traits.
b.
Environmental factors can determine if a genetic trait becomes a health issue.
c.
Environmental factors are determined by genetic traits.
d.
Environmental factors have no influence on genetic traits.
Please select the best answer from the choices provided
A
B
C
D
Answer:
A
Explanation:
Environmental factors determine all genetic traits. Why? So the organism that is gaining the trait has a better chance of survival or to be more specific a better chance at adapting to their environment. Let me give you an example, the long necks on a giraffe. The diet of a giraffe consist of mostly acacia leaves which are leaves that are on the top of a tree. This environmental factor is why giraffes have long neck so they can get to the leaves of the tree. If they did not have long necks giraffes probably would´nt survive
Now let me give you an example that is related to evolution
Evolution is the change in the characteristics of a species over several generations
An example of this happening can be shown in mosquitoes
People were using DDT (which is an insecticide used to kill bugs) on mosquitoes to harm them. Many of the mosquitoes had died but the remaining were able to produce offspring that had mutations. These mutations caused the mosquitoes to be resistant to the insecticide. This shows another example of environmental factors having an influence on genetic traits. The DDT spray was the environmental factor and the mosquito being able to produce offspring that were resistant the the insecticide is the outcome from the influence.
