Answer:
Human X and Y chromosomes determine the biological sex of a person, with XX specifying female and XY specifying male. Although the Y chromosome contains a small region of similarity to the X chromosome so that they can pair during meiosis, the Y chromosome is much shorter and contains many fewer genes.

Which statement best explains why Earth’s outer core is in liquid form
what are the statements?
True or false an objects color is dependent on the chemical composition of its matter which determines the wavelength that is reflecteded
Answer: True
Explanation:
This statement is true.
What do you mean by wavelength?Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. In wireless systems, this length is usually specified in meters (m), centimeters (cm) or millimeters (mm).
Moreover, the wavelength of light is defined as “The distance between the two successive crests or troughs of the light wave”. It is denoted by the Greek letter lambda (λ). Therefore, the distance between either one crest or trough of one wave and the next wave is known as wavelength.
Hence, the distance between one peak and the next in a series of waves, or the distance between one trough and the next. It's also one of the “yardsticks” used to measure radiation.

Why is the conservation of genetic information during DNA replication important?
Answer:
please give me brainlist and follow
Explanation:
The first method, conservative replication, had the DNA strand completely conserved. Two old DNA strands stuck together, and two new DNA strands were synthesized and stuck together. The old and new DNA did not bind to one another. Another method, dispersive replication, did have old and new DNA binding to each other.
The conservation of genetic information during DNA replication is important, as DNA replication is the process by which cells make copies of their genetic material that pass on to the next generation.
What is the significance of the conservation of genetic materials?The conservation of genetic information during DNA replication is important for maintaining the stability of the genome, preventing the accumulation of harmful mutations, and allowing evolution to occur. The genetic information must be accurately passed down from generation to generation and is also useful adapt to changing environmental conditions.
Hence, the conservation of genetic information during DNA replication is important, as DNA replication is the process by which cells make copies of their genetic material that pass on to the next generation.

What are the enzymes in the mouth
Examples of digestive enzymes are:
Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
Pepsin, produced in the stomach.
Trypsin, produced in the pancreas.
Pancreatic lipase, produced in the pancreas.
Deoxyribonuclease and ribonuclease, produced in the pancreas.
One may also ask, what type of molecule are enzymes made from? proteins
One may also ask, what enzymes are found in the Oesophagus?
The esophagus produces no digestive enzymes but does produce mucous for lubrication. The acidic environment in the stomach stops the action of the amylase enzyme. , sucrases, and lactases, which are also present in the brush border of the small intestinal wall. Maltase breaks down maltose into glucose.
How is saliva produced in the mouth?
You make saliva when you chew. Sucking on a hard candy or cough drop helps you make saliva, too. The glands that make saliva are called salivary glands. The salivary glands sit inside each cheek, at the bottom of your mouth, and near your front teeth by the jaw bone.
What are molecules and how are they used in running? Evidence
What is homeostasis and how does homeostasis work to maintain internal stability? Evidence
Answer:
Osmosis helps cells maintain homeostasis because a cell needs to maintain a specific water balance so that chemical reactions can take place. Osmosis can also be used to balance out the concentration of other molecules (such as sugar or salt) present on either side of a cell membrane.
Explanation:
Homeostasis is the ability of a system to regulate its internal environment through maintaining a stable, relatively constant set of properties such as temperature and PH. Key Terms homeostasis : The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium, such as the ability of warm-blooded.

If you have a transfer RNA molecule with the anticodon AAG what is the amino acid being carried in during elongation?
Answer:
The correct answer would be - Phenylalanine
Explanation:
The amino acid is formed during the process of translation that requires mRNA and tRNA sequences to make a three-base sequence code of amino acid which is complementary to the mRNA sequence triplet code.
mRNA sequences are complementary to the DNA sequence and tRNA sequences but tRNA sequences called anticodons and they have uracil instead of thymine which makes them different from DNA.
So, anticodon is - AAG
mRNA would be - UUC, (DNA would be - AAG)
then triplet code UUC is code for Phenylalanine amino acid.

Which of the following is not a type of asexual reproduction?
O fragmentation
Ofission
Ofertilization
O budding
Help please
Answer:
Fertilization
Explanation:
Binary fission is when single parent cell doubles it’s DNA, then divides into two cells. (usually in bacteria).
Budding is the small growth on surface of parent breaks off, resulting in formation of two individuals. (ex: yeast)
Fragmentation is when organisms break into two or more fragments that develop into a new individual. (occurs in many plants and some animals like starfish)

dna samples from four different organisms were analyzed using a procedure that separates the dna in each sample by size.What procedure was used to obtain these results?
Answer:
The correct answer is - Gel electrophoresis.
Explanation:
Gel electrophoresis is a lab technique used to separate distinct samples of mixed DNA, RNA, or proteins on the basis of their size. In gel electrophoresis, the molecules to be move from one another by an electrical field through a gel with small pores in it. DNA molecules are negatively charged so they move towards positive charge wells in the electric field and get separated.

Why is overfishing dangerous?
Answer:
If you're overfishing at the top of the food chain, and acidifying the ocean at the bottom, you're creating a squeeze that could conceivably collapse the whole system that's my answer
Answer: If over-fishing occurs it can create a void in the food chain. For example, if someone over fishes salmon, then the bass that eat said salmon can starve, and die off, then others predators that eat bass can starve and die off as well. It's a chain reaction like with the dinosaurs. How the ashes from the meteor killed the plants and then the herbivores died, then the Carnivores and omnivores starved and died as well. The chain reaction starts with one thing, over-fishing to fish, is like the meteor to the dinosaurs.

(NO FILES PLEASE) All organisms' cells contain DNA. Every organism's DNA is made of nucleotides. Although, the four species on this phylogenic tree are different, which components of their DNA are the same?
Question 4 options:
(A) sugar deoxyribose and the base thymine.
(B) sugar deoxyribose and the base uracil.
(C) sugar ribose and the base thymine
(D) sugar ribose and the base uracil.
The components of DNA that will be similar in the given organisms will be deoxyribose sugar and base thymine. So the correct answer is option A.
This is because humans, chimpanzees, and gorillas have DNA as their genetic material. And DNA is composed of a phosphate group, a deoxyribose sugar, and the four bases adenine, guanine, cytosine, and thymine.The sugar ribose is not found in the DNA and is known to occur in the RNA. Also base uracil is not found in the DNA.
So ribose sugar and uracil base can never be found in the genome of the organisms which posses DNA as their genetic material.
