Answer:

mitochondria contain membrane folds called cristae, whereas chloroplasts contain vesicles in stacks called grana  

Explanation:

Mitochondria are composed of two membranes (i.e., the inner and outer membranes), which are separated by the intermembrane space. The inner mitochondrial membrane is composed of several folds that form the cristae, which extend into the mitochondrial matrix. On the other hand, in chloroplasts, the inner membrane consists of interconnected stacks of sacs named thylakoids, whose arrangement is known as grana.

Explanation:

By definition of photosynthesis, oxygen is not a reactant needed for photosynthesis.

First, you have to know that photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.

With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.

Photosynthesis takes place in 2 stages:

Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.

This is sunlight, carbon dioxide and water are reactants needed for photosyntesis, and oxygen is not a reactant needed.

Explanation:

DNP and cyanide are both cellular respiration inhibitor.

Cyanide is a neurotoxin that can prevent cellular respiration by it's inactivation activity on mitochondria enzymes called cytochrome oxidase.

DNP (2,4-Dinitrophenol is a chemical that inhibit cellular respiration. It help to shuttle proton across cell membranes of living cells by spreading the proton along along the mitochondria and collapsing the force that produced energy for the cell activities.

Answer:

stable

Explanation:

Another word that can be used to describe homeostasis is - stable

It is an organism's process of maintaining a stable internal environment suitable for sustaining life. It describes the internal stability of an organism.

Most of the homeostasis process is maintained by the cell membrane by allowing what or what not to enter or exit in the cell, however, the complete cell takes part in the homeostasis.

Answer:

Facilitated diffusion

Explanation

Generally when molecules undergo passive diffusion along their concentration gradient,and aided by the cell membrane which provide hydrophillic areas for the molecules to pass through,this is called  facilitate the diffusion.The membrane would be impermeable to these molecules without the proteins,

It is a special transport mechanism for large molecular substances like glucose and Amino acids and ions  e.g Na+ and K+.Therefore facilitated mean to aid,thus the membrane proteins aids or help molecules to pass through.

Channel protein and carrier proteins are the two type of protein involved in the transport.They are specific for each molecules,and would only allow the passage of one molecule or ion through.

Energy is not needed for this to occur place the molecules of glucose are moving along the concentration gradient.

Specifically channel proteins are fixed in shape,some are gated.They are water filled pores Carrier proteins are flexible and adjust their shape to the two media for transport.Thus if the concentration of substances to be transported i s higher on on side A of the cell membrane proteins,the carrier protein will be open to  that side to convey the molecules across.

The amount of molecules transported depend on the amount of the  carries and channel protein available.

Explanation:

This makes sense because this portion of the endoplasmic reticulum builds lipids, or fats, rather than proteins, and thus doesn't need ribosomes. These lipids may include fatty acids, phospholipids and cholesterol molecules. if incorrect dont hate on me please

Explanation:

Diffusion is an example of

a) passive transport

Answer:

[tex]\boxed {\tt A. \ Passive \ transport }[/tex]

Explanation:

First, let's define diffusion.

Diffusion is the movement of particles from areas of high concentration to low concentration. This movement is also known as moving down a concentration gradient. This process of diffusion occurs without any energy.

Since it doesn't require energy expenditure, diffusion is an example of passive transport.

Therefore, the correct answer is A. passive transport.

Answer:

Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis.

Explanation:

Pollen grains contain the male gametes of a sexually reproducing plant. Pollen grains are haploid cells in nature produced by the meiotic division of microspore mother cells (located in the anther). The meiosis of these diploid (2n) microspore mother cells give rise to four haploid microspores. This process in plants is called microsporogenesis.

Each haploid microspore (n) develops into pollen grain called microgametophye (bearing male gamete) via mitotic division. During the pollen grain formation, a wall is formed around the microspores.

Answer:

D. 204

Explanation:

proportion : 12/70 = 35/x

70(35)=12x

2450=12x

204.166667=x and round it to make it 204.

The best estimate of the number of fish in the pond is 204. Thus, option D is correct.

Calculation:

proportion : 12/70 = 35/x

70(35)=12x

2450=12x

204.166667=x and round it to make it 204.

Average speed has been defined as the total distance travelled in total time taken it means that we can calculate the average speed obtained by an object .

Mathematically,

Average Speed = Total distance travelled/Total time taken

It's S.I unit is meter/second

Average speed is a scalar quantity it means that it has only magnitude not direction.

Ecosystem has been the branch of science that deals with the study of relationship between living organisms and natural phenomena. Ecosystem has the system in which both living as well as nonliving organisms are present in a particular location.

Green plants contain chlorophyll and they prepare there own food in the presence of sunlight and the process is known as photosynthesis. In the process of photosynthesis light  energy converted into chemical energy.

Therefore, The best estimate of the number of fish in the pond is 204. Thus, option D is correct.
