Answer:
Diploid
Explanation:
Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half!

Considering the drifting of continents, how do you explain the abundance of marsupials and the absence of native placental mammals in Australia
Answer:
this phenomenon is a natural consequence of evolutionary processes and continental drift
Explanation:
Marsupials are mammals in which newborn offspring are carried in a pouch of the female (mother) body. On the other hand, placentals are mammals that complete embryo development in the mother's body, in the placenta. All the extant marsupials are endemic to Australia and the Americas. It has been shown that marsupials diverged (evolved) in South America, Australia and Antarctica when these landmasses were joined. In Australia, marsupials evolved to fit an ecological niche, which can be attributed to geographic isolation due to continental drift, while placental mammals are relatively recent and more scarce (mainly bats and rodents) within this region.

Explanation:
138) Six-year-old Matthew broke his femur and one of his epiphyseal plates was damaged. Explain the role of the epiphyseal plate in longitudinal growth and predict the effects of a damaged epiphyseal plate on his future longitudinal growth.
Answer:
The function of the physis or growth plate is to allow the growth in length of the bones (both long as short) through the endochondral ossification process.
Explanation:
The epiphyseal plates are areas of active growth of new bone at the ends of the bones, made up of cartilage that hardens once the child is fully developed. Epiphyseal plates help determine the length and shape of the adult bone eventually. It is the last part of the bones to harden, and therefore they are vulnerable to fractures. The complication of the involvement of the growth plate is the deformity or lack of growth of the bone, leaving the limb twisted or shorter than the contralateral one.Growth disturbances are more frequent when the affected area is very large or when it involves the area of the knee joint. In cases of shoulder or wrist involvement, deformities rarely occur. The alterations are more common when the lesions occur in younger children, because they have a longer growth period.

The bacterial RecA protein (and its counterpart in eukaryotes, Rad51) are involved in, and help direct: ________.
a. chromatin packing and heterochromatin formation
b. Apurinic site repair
c. Post-transcriptional regulation
d. Strand invasion
Answer:
The appropriate alternative is Option b (Apurinic site repair).
Explanation:
Although these antibodies eliminate compromised DNA bases through midriff of N-glycosylic attachments, maintaining perhaps an apurine or perhaps even apyrimidine site today.RecA connects towards DNA damage as well as precipitates recombinant restoration through doulas branch fracture pairing or daughter strand difference restore.Other solutions aren't relevant to the situation in question. So that the answer above is the right one.
If a female fruit fly is heterozygous with the allele for white eyes being recessive and the red eyes being dominant on the X-chromosome. She is crossed with a hemizygous red eyed male, what would be the expected ratio of male and female phenotypes if they were bred together?
Answer:
100% red eyes because there is 50% AA and 50% Aa.
Explanation:
To find the expected ratio of male and female phenotypes if they were bred together, you need to make a punnett square/table.
Female: A a
"A" is white eyes, which is RARE. "a" is red eyes, which is COMMON.
Male: A A
"A" is red eyes, which is COMMON.
Multiply Aa x AA by a punnett square.
GUIDE:
1. AA is common and does not carry the recessive gene of being white-eyed. 2. aa is rare and carries the recessive gene of being white-eyed.
3. Aa is common as being red-eyed since being red-eyed is dominant, but carries the recessive gene of being white-eyed.
Having freckles is a dominant trait, and not having freckles is a recessive trait. Which set of parents will not have any children with freckles? A. A mother with FF and a father with ff O B. A mother with Ffand a father with Ff O c. A mother with ff and a father with ff
As freckles are a dominant trait, they will not occur in the children with a homozygous recessive trait, i.e., ff. The correct option is C.
What are recessive traits?Recessive trait is a trait that really should be transmitted by both parents in order to be present in the offspring. Recessive features might exist in a person's DNA but not manifest in that individual.
As in the given case, F denotes dominance, and f denotes recessive character. Dominant trait always superimpose over the recessive one.
So, as freckles are a dominant trait, they will not occur in the children with a homozygous recessive trait i.e., ff.
Thus, the correct option is C.

Using the diagram below, identify the ONLY portion of the nucleotide that is not the same in every piece of DNA. (phosphate, sugar, or base)
Answer:
Base
Explanation:
Deoxyribonucleic acid, DNA, is one of the four major biomolecules in living organisms. It is a polymer made up of monomers called NUCLEOTIDES. The nucleotides that make up a DNA molecule is composed of three substances namely: Sugar (deoxyribose), nitrogenous base, and a phosphate group.
However, among these three components of the nucleotide monomer, NITROGENOUS BASE is the only portion that is not the same in every DNA molecule. There are four nitrogenous bases in nature viz: Adenine, Guanine, Cytosine and Thymine. These four bases can be alternated in a DNA molecule.
Note that, phosphate group and deoxyribose sugar are constant in every DNA.

Collenchyma

Answer:
The correct answer is - Sclerenchyma
Explanation:
Sclerenchyma are the dead cells with narrow lumen lignified cells. These dead cells has numerous pits that helps in trading the various substances to neighboring cells. At matuarity, hese cell lack the protoplast so therefore called dead cells .
Sclerenchyma cells are lignified which makes them thick and these cells help in the supporting the plants. These cells are impereable to almost everything gases, substances and many more.

A)
use the acid test
B)
see if it breaks into sheets
C)
see if it is attracted to a magnet
D
compare the color to other minerals
Answer:
The correct answer is - a) use the acid test.
Explanation:
In this chart, there are many minerals that share different properties with one another such as hardness, color, and luster of the minerals so on the basis of physical properties the group of students can not be sure if the given mineral is calcite or not.
To be sure if the given mineral is calcite the group of students must test the acid test which is specific for the calcite and if the test produces bubbles it is confirmed that the given mineral among these minerals is calcite.
white eyes are recessive in flies. can two red eyed flies have white eyed offspring
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies :
Red eye (R) is dominant trait. White eyes (r) is the recessive trait.When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square :
Rr X Rr
Alleles R r
R RR Rr
r Rr rr
In the offspring, the probabilities are:
50% heterozygous individuals Rr, with red eye phenotype. 25% pure dominant individuals RR, with red eyes 25% individuals with the recessive rr genotype, white eyes.This is the possibility of two red-eyed flies having white-eyed offspring.
