D. A decrease in the rate of the light reactions

The Diagram Summarizes The Steps Of Photosynthesis Inside Chloroplasts. IF A Chloroplast Does Not Have

Answers

Answer 1

If a chloroplast does not have enough hydrogen ions, there will be a decrease in the production of sugar that is present in Option A because glucose production needs lots of ATP.

What is the importance of the hydrogen ions?

The hydrogen ion gradient is generated when the electrons move in the light reaction through the different complexes, and then these ions move from the inside of the matrix to the outside and generate ATP with the help of ATP synthase. If hydrogen ions are absent, then ATP can't be formed and glucose synthesis is hampered.

Hence, if a chloroplast does not have enough hydrogen ions, there will be a decrease in the production of sugar that is present in Option A because glucose production needs lots of ATP.

What makes a seedling different from a plant?

The seedling is a small plant resulting from the early development of the embryo. A seedling is considered when most of the compounds necessary for its development still come from the cotyledons, that is, when more than 50% of the cotyledons are still present and functional.

In asexual reproduction, the plant does not need another gamete to reproduce. For this type of reproduction, parts of the plant are removed to obtain new plants, which is known as a clone. This case occurs in Kalanchoe plants produce plantlets on their leaves.

Identify the 3 types of natural selection indicates by each graph (please include written descriptions of each!!)

Answers

Answer:

Graph A: Directional Selection

Graph B: Stabilizing Selection

Graph C: Disruptive Selection

Explanation:

Natural selection as a driving force of evolution cam be defined as a process that a population of organisms undergo in other to become adapted to an environment and survive to produce offspring that are fitter.

Thus, the following graphs represents the three types of natural selection:

Graph A: Directional Selection

Directional selection occurs when one extreme trait is favoured over others by selective pressures.

The graph shows that only one extreme trait is favoured as the population that survives seem to have majorly a particular extreme trait.

Graph B: Stabilizing Selection

In this type of natural selection, neither of the extreme traits are favoured by selective pressures. Therefore, intermediate trait become favoured over the other extreme traits.

Graph C: Disruptive Selection

Selective pressures works against the intermediate trait while both extreme trait at the spectrum are well favoured, which become more established in a population against the intermediate trait.

Explanation:

Consider two kinesin motor proteins at the mitotic spindle midzone: kinesin A is a tetrameric motor that walks toward the plus end of both microtubules to which it is attached via its motor domains; kinesin B, on the other hand, walks toward the minus end of one microtubule while it is attached to another microtubule via its tail domain.How do these motors affect the length of the spindle?
A. They both work to shorten the spindle.
B. Kinesin-5 works to shorten the spindle whereas kinesin-14 works to lengthen it.
C. Kinesin-5 works to lengthen the spindle whereas kinesin-14 works to shorten it.
D. They both work to lengthen the spindle.

Answers

Answer:

C. Kinesin-5 (kinesin A) works to lengthen the spindle whereas kinesin-14 (kinesin B) works to shorten it.

Explanation:

Kinesins are microtubule-based motors localized in the mitotic spindle in order to ensure the correct segregation of the chromosomes during cellular division. These proteins are classified regarding their sequences at the core motor domains which determine their motility. Kinesins can move along microtubules in opposite directions, walking toward the plus end (i.e., the end that grows more rapidly) or moving toward the minus end. Recently, it has been shown that opposite forces between kinesin-5 (plus-end-directed) and kinesin-14 (minus-end-directed) microtubule-based motors regulate the length of the spindle during cellular division. Kinesin-14 is a minus-end-directed motor protein that walks along microtubules from plus- to minus-end, while kinesin-5 is a plus-end-directed motor protein that walks along microtubules from minus- to plus-end, and thereby they work to shorten and lengthen the mitotic spindle, respectively.

Explanation:

Species is a group of population in which organisms have many common characteristics and they are capable of interbreeding and producing viable fertile offsprings. The members belonging to the same class and phylum have less common characteristics if they interbreed they may not produce viable fertile offsprings. Also, the organisms of the same kingdom have least common characteristics and will not have viable fertile offsprings after interbreeding.

Scientists build models based on what they know from previous research to derive testable hypotheses. Independently, both Watson and Crick and their competitor Linus Pauling constructed an incorrect triple helix model with the nitrogenous bases arranged so they were on the exterior of the molecule and the phosphate groups on the interior. Although their model was wrong, what assumption made it reasonable to build a model with the bases projecting to the outside

Answers

Answer:

Nitrogenous bases contain the genetic information, their amount is variable among different species, and the arrangement of these bases is also variable among different species

Explanation:

Both Watson-Crick and Pauling's DNA models considered that DNA nitrogenous bases (i.e., Adenine, Cytosine, Thymine and Guanine) contain the genetic information that determines the characteristics of living organisms. Moreover, both DNA models also considered that nitrogenous base composition varies between species, as well as the arrangement of these bases in the DNA chain also varies between species. Based on these features, Linus Pauling considered that a model where nitrogenous bases would be arranged on the outside of the DNA molecule would be easier for the DNA molecule to be replicated, transcribed, or repaired. Although incorrect, Pauling's DNA triple helix model was fundamental to develop the helical (double-stranded) structure of DNA, which was finally discovered by Watson and Crick in 1953.

Which of these islands would likely have the most species diversity.
A small island in the middle of the ocean
O A large island near the mainland

Answers

Answer:

A large island near the mainland

Explanation:

A large island has a greater number of species, a greater interaction between them and a greater number of natural elements. All of this is capable of promoting biological specialization on a large scale, allowing new species to emerge more quickly than on a small island. Although a small island may also have great biodiversity, that island has fewer factors that promote the creation of new species, in addition to having fewer species interacting and creating new species.
