In the testes, sperm cells replicate and differentiate in the _________. Question 2 options: urethra septum tunica albuginea seminiferous tubules ductus deferens
Answer:
seminiferous tubules
Explanation:
Seminiferous tubules are coiled tubes where sperm cells are produced by a process referred to as spermatogenesis. These tubes are located in the testes or testicles (i.e., male reproductive glands/gonads). Each testicle contains approximately 250 compartments known as testicular lobules, while each testicular lobule has 1 to 4 seminiferous tubules which converge to form a single straight tubule. Once sperm cells mature, they travel through the seminiferous tubules to be stored in a coiled tube called the epididymis.
hypothesis on what is the effect of the genes of the parental mice on the fur color of the offspring mice? use "If...then...format
Answer:
If the GENES of the parental mice encodes for a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Explanation:
Hypothesis is one of the steps used in the scientific method. It is a testable explanation of a given question or observation. Hypothesis in an experiment must be subjected to testing via experimentation in order to determine whether to reject it or not.
Hypothesis is usually constructed in the IF, THEN format. It tells us how the independent variable (cause) affects the dependent variable (outcome). In this case, a question is asked this: "what is the effect of the genes of the parental mice on the fur color of the offspring mice?"
A possible hypothesis will be: If the GENES of the parental mice encodes a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Answer:
A. If either parent mouse passes a dominant allele, the offspring will have black fur.
Explanation:
Either option is correct because it didn't show any green check. It determines on what hypothesis you wrote. I chose A because it relates to my statement. <33

tRNA molecules deliver amino acids to ribosomes where the amino acid next
A. forms an ionic bond with another amino acid
B. is deaminated and catabolized
С. becomes an anticodon
D. is covalently bonded to a growing polypeptide
E. forms hydrogen bonds with esters
Answer:
tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).
Explanation:
A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.
What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.
tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.
During translation tRNA, molecules deliver amino acids to the ribosome and bind to this codon. It is a complementary anticodon to this codon.
Each tRNA molecule has two distinct endsone end binds to a specific amino acidthe other which binds to the corresponding mRNA codon. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.Thus, tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.

Answer:
B
Explanation:
The theory,of evolution states that all living things had a single common ancestor. The translation between mRNA and amino acids is the same for all living thing. Does the second statement support the theory of evolution ?
Answer: the theory of evolution states that all living things we can identify descend from the Last Universal Common Ancestor. It is not that the translation process between mRNA and amino acids is universal, but that the underlying genetic code relating DNA nucleotide triplets (codons) to amino acids is the same for almost all living things.
Explanation: The genetic code ‘tells’ mRNA which the sequence of amino acids in a protein and when to stop adding amino acids. The DNA . triplets, called codons, code for 20 amino acids and a STOP signal. The code is identical in almost all cases, but there are variation, mostly found in mitochondrial DNA. But even when these variants exist, most of the code is the same as in other living organisms. For example the codon AGG normally codes for the amino acid serine but in arthropod mitochondria it codes for lysine. These very few and minor changes tend to confirm the single ancestry of the code and how well it has been conserved through billions of replications

How do mutations affect natural selection
Answer:
The idea of natural selection would in theory be affected by mutations because natural selection invloves a species/animal only surviving by having a certain trait. Over time, all of the animals/species would have this trait through elimination partnered with reproduction. A mutation may begin this cycle by giving an animal the ability to have an advantage over its fellow species.

Explanation:
Fred has inherited the colorblind trait from his mother. We know this because his spot on the pedigree is filled in. Because he is a male his genotype must be some variation of xy and because he is colorblind he must have the recessive "h" on his x chromosome. So his genotype (genetic type) is [tex]x^{h} y[/tex]
The pathophysiology of osteomalacia involves a. collagen breakdown in the bone matrix. b. inadequate mineralization in the osteoid. c. crowding of cells in the osteoid. d. increased osteoclast activity.
Answer:
The correct answer is - b. inadequate mineralization in the osteoid.

What is the best explanation for the difference in shape between the two drops shown below
Answer:
A
Explanation:
I think the answer is A because Hexane is a non-polar solvent and A is the only answer choice that says its non polar. Im sorry if it is incorrect
The best explanation for the difference in shape between the two drops given in image is - Option D. glycerin is polar and has greater cohesion than hexane.
Polarity is the physical characteristics of liquid that allows them to stick to other substances which is called adhesion. Polar molecules also attracted to itself, and this physical trait called cohesion. Water's most common form in the air, a droplet is formed due to this cohesion.
Hexane is a nonpolar solvent that has less electro negativity charge therefore, they do not have hydrogen bonding and there is less cohesion in the molecules.Glycerin is a polar solvent that allows its molecules to attract itself that is cohesion present and lead to more of droplet shape.Thus, the correct answer is - option D.

If there will be changes on trophic levels, what will be the effects on the ecosystem?
Answer:
It can significantly alter the homeostasis of the ecosystem
Explanation:
The trophic level is the position that occupies a given organism/ population/species in the food web. In a food web, the trophic levels are organized into a first category (formed by primary producers, e.g., plants), a second level (primary consumers, e.g., herbivores), and subsequent categories (predators, e.g., carnivores). The abrupt change in the number of organisms belonging to the same trophic level generally has a negative effect on the ecosystem by modifying the trophic structure of communities. For example, decreasing the number of producers will produce a decrease in the number of primary consumers, thereby altering the homeostasis (equilibrium) of the entire ecosystem. On some occasions, it may eventually lead to the extinction of populations and species.
