Why are animal gametes haploid?
a. Gametes have two copies of each chromosome
b. Gametes are developing embryos that develop into haploid adults
c. Gametes have one copy of each chromosome to create a haploid individual
d. Haploid egg and sperm cells combine to create a diploid individual
Answer:
d. Haploid egg and sperm cells combine to create a diploid individual
Explanation:
Animals are diploid organisms (2n) and undergo sexual reproduction. This sexual reproduction causes them to produce gametes via a process called MEIOSIS. Meiosis is a division that reduced the number of chromosomes in the daughter cell (gamete) by half.
This means that meiotic division produces haploid gametes (n) from a diploid animal. This happens so that when the haploid sperm cell (male gametes) and haploid egg cell (female gametes) meet in a process called FERTILIZATION, a diploid individual is created.
Answer:
D. Haploid egg and sperm cells combine to create a diploid individual
Explanation:
Which statement is correct regarding the semiconservative nature of DNA? Best answer will be marked brainliest
A. Nitrogenous bases in each “parent” strand serve as a template for the new strand to be made
B. The semiconservative nature of DNA allows DNA to stay the same during gamete (egg and sperm) production
C. RNA operates as a template to allow DNA to replicate itself using ribosomes
D. The structure of the sugars on the DNA molecule direct the correct nucleotides into place during replication
The semiconservative nature of DNA means that Nitrogenous bases in each
“parent” strand serve as a template for the new strand to be made
The semiconservative nature of DNA means that the DNA has two helices
which are created from one strand of the helix. The other DNA acts as a
template in which the new DNA is copied from.
A new DNA double helix consists of a hybrid of one strand of old DNA which
are bound to one strand of newly synthesized DNA to ensure the daughter
cells have unique features.
This feature makes DNA profiling important in identification as individuals
have a unique DNA.

Explanation:
The flame of many stove burners is blue, but the wires of a toaster glow orange. How do you think the temperatures of these two cooking appliances compare?
Answer:
the hotter is it, the more bluish it is. And the more reddish it is, the colder it is
just like the bluer the star, the hotter it is, the redder the star, the colder it is.
Comparing the temperatures of the two cooking appliances ; The temperature emitted in stove burners are hotter than the temperatures emitted by the toaster
White-Blue flames are the hottest flames when combined together but the hottest single flame is the blue flame burning between ( 2,600º F and 3,000º F). Blue flames have more oxygen than other types of flames, hence they burn hottest and this is because gases when burnt are hotter than other materials. while
The orange flame of a toaster burns at a temperature between ( 1100°C to 1200°C) . releasing carbon monoxide as it burns.
Hence we can conclude that The temperature emitted in stove burners are hotter than the temperatures emitted by the wires of a toaster.

Which type of sensory receptors monitor position and movement of the body?
A. Photoreceptors
B. Chemoreceptors
C. Proprioceptors
D. Exteroceptors
Answer:
C. Proprioceptors
Explanation:
Firstly option A. Photoreceptors - Is responsible for our vision and is a subcategory for option D. Exteroceptors.
External receptors that respond to stimuli from outside the body are called exteroceptors.
Option C. is the correct answer because Proprioceptors is the sense of self-movement and body position. It sometimes may also be referred to as our sixth sense.

I don’t understand biology at all and I am worried about how to pass biology . Does anyone have study tips for biology or anyways that can help me relearn everything
Answer:
Biology is not a hard class however it does require memorization and comprehension of certain topics. I recommend that you read over the chapters and make flashcards and test yourself. You can also ask your teacher for help. There are many videos available that do a great job at explaining each topic in biology. In addition, there are various websites that can also provide information. You should make study groups with your classmates as it is a more fun and effective way of studying.
Answer:
Firstly, don't stress, you'll get through it. Worrying will just slow you down, and learn Biology as something you get to do, and not a chore.
And if you want to relearn everything from the beginning, then I would recommend Crash Course's free Biology courses on YT, they also have Chemistry courses and everything. You can also go to Ask a Biologist, where you can do more than just ask questions.
There are so many more sources of information and everything, but one thing is; don't stress, that's the key.
Good luck, stay safe and healthy.
You'll get through it! Don't worry. If you want me to recommend more websites to you, just comment on this answer :D

The formation of sea ice removes freshwater and dissolved solids from seawater, leading to a decrease in density. The correct option is C.
What is salinity?The concentration levels of salts in water or soils are referred to as "salinity."
Salinity is classified into three types based on its cause: primary salinity (also known as innate salinity), secondary salinity (also known as dryland salinity), and supplementary salinity (also called irrigation salinity).
When the water table rises, natural salts rise to the surface; in sufficient quantities, these salts become toxic to most plants.
As a result, the surrounding seawater becomes saltier because salt is left behind when sea ice forms.
As seawater becomes saltier, its density rises and it begins to sink. Surface water is drawn in to replace sinking water, which eventually cools and salts enough to sink.
Thus, the correct option is C.

A woman of childbearing years who is not pregnant has _______ absorption rate of calcium as compared to a woman who is pregnant
Answer:
The correct answer is - lower
Explanation:
Pregnant women require an increased amount of calcium as it can provide a sufficient amount of calcium for herself and her fetuses. During lactation, the calcium is reabsorbed very fast and rapidly that supplies the calcium for the milk. So, the normal women of childbearing age do not require the amount of calcium as pregnant women require.
Thus, there is a lower absorption rate of calcium as compared to a pregnant women

Why is it important for the daughter cells to divide a second time In meiosis?
Answer:
The second time the daughters cells divided haploid cells form and then migrate to other haploid cells in the process of fertilization.
Explanation:
Daughter cells divide a second time In meiosis because it creates cells that are destined to become gametes.
What is Meiosis?This is the type of cell division common in reproduction and gamete production and produces four unique daughter cells.
The daughter cells divide twice because it creates cells that are destined to become gametes as its union during fertilization would result in offspring with twice the normal number of chromosomes.

The figure above represents a rough endoplasmic reticulum. Which of the following best describes the role of the structure labeled Y
Answer:
The figure is absent in this question, however, it can be answered based on general understanding of the structure of rough endoplasmic reticulum. The options are:
A) Structure Y contributes the raw materials required for the synthesis of proteins
B) Structure Y packages proteins for export from the cell
C) Structure Y is the location where proteins are synthesized
D) Structure Y contains enzymes that cut and bind proteins.
The answer is C.
Explanation:
The rough endoplasmic reticulum is one of the two types of the endoplasmic reticulum, which is a part of the endomembrane system found in eukaryotic cells. The rough endoplasmic reticulum is so named "rough" because of the structures attached to its surface.
The structures attached to the surface of the rough endoplasmic reticulum are the structures labelled Y in the figure of this question. Those structures are called RIBOSOMES and they are the site (organelles) of protein synthesis in living cells. Therefore, structure Y is the location where where proteins are synthesized.
