Answer:

A. Species.

Explanation:

A species is classified as being able to interbreed together. In this case, a human boy and a human girl can interbreed.

Offspring does not make as much sense in this case, for there is no context to allow it to be the correct answer. Boys and girls are technically terms used for kids, which equate to offspring, however it is not your answer.

Boys and girls also are not the same gender. They equate to the norm of gender binary, which means that there are two genders, being male (boy) and female (girl). As by definition, this is not malleable, and individuals fit into one or the other typically based on natural development.

Therefore, Species is the only satisfactory answer in this case.

To which substance does ferredoxin transfer an electron?
Sonbull [250]

The right answer is NADP+.

Ferredoxin is an iron-sulfur protein that effects electron transfer in a large number of redox reactions in cell metabolism through Fe-S clusters whose iron cations oscillate between +2 (ferrous) oxidation states. and +3 (ferric). The first protein of this type was isolated in 1962 from the anaerobic bacterium Clostridium pasteurianum. A chloroplast-specific ferredoxin is involved in the cyclic and noncyclic photophosphorylation reactions of photosynthesis. In non-cyclic photophosphorylation, ferredoxin is the ultimate electron acceptor and reduces NADP + under the action of ferredoxin-NADP + reductase (EC 1.18.1.2) with FAD and a flavin group as cofactors:

2 ferredoxin- [Fe (2+) Fe (3+) S2 (-2)] + NADP (+) + H (+) ==> 2 ferredoxin- [Fe3 (+2) S2 (-2)] + NADPH .

1. In eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are microtubules. 2. Ma
yulyashka [42]

Answer:

1) In eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are microtubules.

2) Many cell organelles, most notably the nucleus, are anchored by intermediate filaments which are assembled from a diverse class of proteins.

3) Centrosomes are sites where protein dimers assemble into microtubules.

4) The extension of pseudopodia in amoeba is due to the regulated assembly and destruction of microfilaments.

5) The only cytoskeletal fibers not associated with intracellular movement or whole cell locomotion are the intermediate filaments.

6) During muscle contractions, myosin motor proteins move across tracks of microfilaments.

Explanation:

The cytoskeleton is a very important element of the cell, and is composed of three different structures: microtubules, intermediate filaments, and microfilaments.

<u>Microtubules</u> are structures in the shape of hollow tubes that <u>give shape to the cell</u>. Microtubules also participate in cell motility by <u>providing a route</u> for the organelles to move through.

Intermediate filaments are the only ones that do not participate in cell motility: their main function is to <u>provide mechanical support for the plasma membrane</u>.

Microfilaments are a key component in <u>cell motility</u>, and also associate with myosin (a protein) to produce <u>muscle contraction</u>. Microfilaments also give the cell the ability to grow <u>pseudopods</u>.

Which best describes the offspring of protists?
Hunter-Best [27]

Options found elsewhere:

-always genetically identical to one parent

-always genetically identical to both parents

-never genetically identical to one parent

-sometimes genetically different than both parents

Answer:

-sometimes genetically different than both parents

Explanation:

Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.

Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.

Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .

If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.

Advantages to using a punnet square
timofeeve [1]
A Punnett square summarizes how the processes of meiosis and fertilization contribute to inheritance of different alleles of a gene. So one major advantage is it can help determine certain things about a child by looking at the dominant and recessive genes and gives a percent of how likely they are to get that thing for example a punnet square may show what color a child’s eye color is likely to be upon birth
