Answer:
seed producing plants
Explanation:
gynosperms also known as a acrogymnospermae are a group of seed producing plants that includes conifers cycads Ginkgo and gnetophytes the term gynosperm comes from a composite word in Greek meaning literally naked seeds.

Answer: Pulmonary veins
The pulmonary veins bring oxygen-rich blood to the left atrium.
Happy to help; have a great day! Please remember to give me Brainliest :)
B - black (both BB and Bb genotypes)
b - albino (bb genotype)
This is a problem showing that 1 phenotype (black color) can be the result of two different genotypes (BB and Bb). These two crosses would be the equivalent of test crosses to determine genotype.
A black guinea pig crossed with an albino guinea pig produced 12 black offspring. This is the result (all black offspring) you would expect when breeding two true breeders (Two homozygotes BB x bb).
B B
b Bb Bb
b Bb Bb
When the albino was crossed with a second black one, 7 blacks and 5 albinos were obtained. This looks like the results you would expect between a heterozygote and an albino (Bb x bb).
B b
b Bb bb
b Bb bb
Answer:
A black guinea pig crossed with an albino guinea pig producing 12 black offspring
b b
B Bb Bb
B Bb Bb
The genotype of the black gunea pig will be BB in this situation and the genotype for the albino pig would be bb.
The gametes formed will be B, B,b, b.
The offsprings will have genotype Bb. They will be heterozygous black.
When the albino was crossed with a second black one, 7 blacks and 5 albinos were obtained
b b
B Bb Bb
b bb bb
The genotype of the black parent will be heterozygous i.e Bb in this condition. The genotype of the albino parent will be bb.
The gametes formed will be B,b,b,b.
50% of the offsprings will have the probability of having heterozygous Bb genotype. 50% of the offsprings will have the probability of having albino bb genotype.
B. small sizes
C. varied shapes
D. methods of movement
Answer: The correct answer for the blank is A.biochemical diversity.
Bacteria can thrive in various environmental conditions such as hot springs, salt flat, polar ice caps because of their biochemical diversity.
For instance, the organisms belonging to the domain archaea ( such as methanogens) live in extremely harsh environmental conditions. They have ether linked lipids in their cell membrane ( unlike bacteria, which possess ester linked lipids) and do not have peptidoglycan in their cell membrane. This provides them an advantage to survive under harsh conditions.
Answer:
I know for a fact it’s not ‘the body replenishes water...’ because I took the quiz and got it wrong, so the ‘verified’ answer is wrong. However, it didn’t let me see the correct answer. :/
B.) They both carry genetic information.
C.) The structure of proteins is determined by nucleic acids.
D.) The subunits of nucleic acids are also the subunits of proteins.
I believe the correct answer is C.) The structure of proteins is determined by nucleic acids.
To understand this answer, we have to go back to a process called protein synthesis which occurs in the ribosome of a cell. To make the proteins, transcription of DNA to mRNA first occurs in the nucleus. A process called translation then occurs which is just reading the mRNA to understand the message it contains. mRNA is usually single stranded and has bases that code for specific amino acids that build up proteins. Making the mRNA from DNA is the first phase of DNA synthesis called transcription. A strand of mRNA is created and complements the strand of DNA. For Example, if the DNA coding was GAC ACT GAC, the complementary mRNA will be CUG UGA CUG. C complements for G, U complements for A and G complements for C. UAGCT are nitrogenous bases or the nucleic acids found in RNA and DNA. Transcription is divided into initiation where an enzyme called RNA polymerase binds to the promoter region signaling the DNA to unwind to enable the enzyme RNA polymerase to read of the 2 strands that make the DNA. Elongation is the second step where nucleotides are added the strand of mRNA with the complementary bases. Termination is the last step and the mRNA strand that complements the DNA is fully completes so it cuts away from the DNA. Translation of the mRNA then occurs so that a protein can be made. The mRNA leaves the nucleus and enters into the ribosome that reads the codons in the mRNA and molecules of tRNA carry amino acids into the ribosome according to how the codons of mRNA are arranged. In end, when the ribosomes translate to the terminating codon, the process of translation ends and a protein is made with amino acids arranged in the correct sequence.

Option (C) The structure of protein isdetermined by nucleic acids is correct answer.
Further Explanation:
The protein is an elongated chain of amino acids that are a necessary part of all living organisms. Protein is the basic structural element of body tissues such as muscles, hair, etc. nucleic acids are macromolecules that store genetic data and modify protein production. Proteins are classified as primary, secondary, tertiary and quaternary proteins according to the types of bonds present in the structure as well as its complexity.
Deoxyribonucleicacid and ribonucleicacid are the nucleic acids composed of nucleotides. The DNA present within the cell's nucleus transcribes itself to make RNA and the RNA translates to make a protein. Carbohydrates are the primary supply of energy within the body. Nucleic acids are nowhere involved in providing energy to the body. The nucleic acids (RNA and DNA) carry the genetic data in an organism. The nucleic acids are made up of nucleotides thymine, adenine, cytosine, uracil, and guanine. Twenty amino acids randomly made up the protein. Some examples of amino acids are alanine, glycine, proline, glutamine, tyrosine, etc. So, the subunits of nucleic acids don't seem to be the subunits of proteins.
Thus, the nucleic acids determine the structure of proteins formed.
