define acceleration. Write its formula and SI unit . pls answer my question!​

Answers

Answer 1

Answer:

the rate of change of velocity with time is called acceleration.

it can also be defined as the increase in velocity per second.

The S.I. unit of acceleration is meter per second square or ms−2.

formula; a = Δv / Δt

where a is acceleration,

Δv is the change in velocity,

and Δt is the amount of time it took for that change to occur.

A bacterial cell wall is composed of: A) A polysaccharide consisting of a single type of monosaccharide unit and cross-linking oligopeptides. B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides. C) A polysaccharide consisting of 3 types of monosaccharide units and cross-linking oligopeptides. D) Two different polysaccharides and 1 type of oligopeptide, which are cross-linked.

Answers

Answer:

B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

Also, a unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

A bacterial cell is made up of peptidoglycan and its main function is to maintain the shape of a cell while preventing it from bursting due to osmotic pressure. Also, the bacterial cell inhibits the passage of larger molecules but allows the free movement (passage) of smaller molecules in the body of a living organism.

Basically, bacterial cell wall comprises a polysaccharide that's typically made up of two (2) types of monosaccharide units and cross-linking oligopeptides.

ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.

Answers

Answer:

A

Explanation:

the sister chromatids separate

After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.

What is Homologous pair?

Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.

In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.

This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.

Therefore, the correct option for this question is A.

It is believed that the ratio of cyclic electron transport to Z-scheme photosynthesis changes in response to metabolic demands. If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, how would it alter these processes compared to a plant just performing the Calvin cycle to produce glucose

Answers

Answer:

The correct answer is (b) More Z-scheme photosynthesis, less cyclic photophosphorylation

Explanation:

Z-scheme is the schematic flow of the electrons from water to NADP+ and as it connects the two different photosystems that look like z in the diagram it is termed as Z-scheme of photosynthesis. The ratio of cyclic electron transport to Z-scheme photosynthesis alters as per the metabolic requirements. In the question, it is given that If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, then it will acqiuire more z-scheme photosynthesis compared to a plant just performing the Calvin cycle to produce glucose.

Answer:  More Z-scheme photosynthesis, less cyclic photophosphorylation

You are overseeing a paleontological expedition at the Grand Canyon to uncover fossils. You have one group working about 10 feet above the bottom of the canyon,
uncovering a cluster of Brachiopods You have a second group working about 300 feet above the bottom of the canyon, uncovering impressions from a variety of plants
such as fems and horsetails. While you are waiting for the exact age of the rock layers to be determined, what can you tell about the age of the fossils based on
where they are
A. You cannot determine anything yet.
B. They are all about the same age.
C. The plants must be older than the Brachiopods.
D. The Brachiopods must be older than the plante

Answers

Answer:

C

Explanation:

because the plants are farther down lol

Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.

What are fossils?

The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.

The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.

The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.

Therefore, option C. the plants existed prior to the Brachiopods.
