Answer:
Option #3
Explanation:
That is the basic terminology that us used during meiosis.
The statement that best describes the correct outcome of this defect is the sperm cells will all be the same. Thus, the correct option for this question is A.
What is Meiosis?Meiosis may be defined as a type of cell division that significantly produces four daughter cells that are genetically non-identical to the parental cells. These daughter cells are haploid in nature. Germ cells or sex cells are generally produced by this mechanism.
The cells that are formed as a result of meiosis have half the amount of chromosomes as compared to the parental cell. This is because when the germ cells of two different origins fuse together, they will form complete chromosomes.
The egg cells or sperm cells that are produced by this process of cell division will all be the same with respect to the number of chromosomes and physiology along with function.
Therefore, the sperm cells will all be the same is a statement that best describes the correct outcome of this defect. Thus, the correct option for this question is A.

Answer:
your answer would be B. the vascular tissue
Explanation:
There are two principal tissue types that make up the veins of plants: The xylem moves water and minerals. This flows from the plant’s roots upwards. The phloem moves food energy around the plant. This flows in whichever direction the plant needs it to flow. These two tissue types make up the vascular bundle of the plant.

How does mRNA help in the differentiation of structures as an organism develops?
A. mRNA creates the amino acid chain that will eventually code for the specific protein that makes up a specific organ.
B.mRNA packages the proteins and takes them out of the cell
C.mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
D.mRNA is stored in the nucleus and carries the genetic code to make all of the specific structures of the body
Answer:
answer is part (C)
Explanation:
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ. Thus the correct option is C.
What is mRNA?
Messenger RNA is referred to as a type of single-stranded RNA which involved in protein synthesis. mRNA is made from a DNA template during the process of transcription (formation of protein from DNA to RNA).
The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery ribosome reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.

Identify which type of natural selection is described in each case below.
Results in the evolution of the species:
Results in new species:
Favors traits at the two extremes:
No increase in diversity:
One extreme trait is favored:
Diversity decreases:
Diversity increases:
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Answer: A) directional selection
B) disruptive selection
B) disruptive selection
A) directional selection
A) directional selection
C) stabilizing selection
B) disruptive selection

Do plants and animals both use cellular respiration? Explain.
Answer:
yea
Explanation:
just took a test today
Answer: yes
Explanation: Plant cells respire the same way animal cells do, but respiration is only one part of the process. To survive, plants also need another chemical reaction called photosynthesis. While both plants and animals carry out cellular respiration, only plants conduct photosynthesis to make their own food.

(_______) stars, however, will last for several billion years, because
they burn their fuel much more slowly. *
Answer:
Smaller
Explanation:
Life Cycle of a Star
Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.

Answer:
Carrier proteins can change their shape to move a target molecule from one side of the membrane to the other. ... The carrier proteins involved in facilitated diffusion simply provide hydrophilic molecules with a way to move down an existing concentration gradient (rather than acting as pumps).

A forest fire took over this forest ecosystem, burning a majority of the trees in the area. How would this forest fire impact different two different consumer populations in this ecosystem?
Answer:
Herbivore and carnivores.
Explanation:
This forest fire greatly affected two consumer populations such as herbivores and carnivores because herbivores has no food available due to forest fire. The unavailability of food for the herbivores leads to the decrease in herbivore population that also adversely affected the population of carnivore ( those organisms that feed on herbivores) so both are affected from the forest fire.

10. A student was observing a cell under a microscope. She claimed the cell she was studying was an animal cell.
Below is her drawing of the cell she observed.
What evidence would best support her claim that the cell was an animal cell?
The cell had no ribosomes.
The cell had no cell wall.
The cell had a vacuole.
The cell had a nucleus.
Answer:
Cytokinesis, or “cell motion,” is the second main stage of the mitotic phase during which cell division is completed via the physical separation of the cytoplasmic components into two daughter cells. Division is not complete until the cell components have been apportioned and completely separated into the two daughter cells. Although the stages of mitosis are similar for most eukaryotes, the process of cytokinesis is quite different for eukaryotes that have cell walls, such as plant cells.

What’s the different properties of hbA and HbS
Answer:
The isoelectric point of normal HbA is 6.9 [91], but HbS has two fewer negative charges per hemoglobin molecule than HbA because glutamic acid residues in the β-chains of HbS were substituted by the valine residues [5], [6]. It shows that HbS has more hydrophobicity than HbA in this condition [10]
