Explanation:
Protons are positively charged so A is right
We know the rest are wrong because neutrons have no charge and electrons are negatively charged.
Answer:
The answer is A.
Explanation:
Lets look at the charges of each part and see which one lines up.
A) The protons in an atom have a positive charge.
B) The nucleus contains the protons and neutrons. Since the neutrons have no charge and the protons have a positive charge, the overall charge of the nucleus is positive.
C) Electrons have a negative charge.
D) The neutrons have a neutral charge meaning they do not have a positive or negative charge.

why does the density of liquid water increase as it cools?
The density has been inversely proportional to the volume of the substance and the temperature. The density of the liquid water increases as it cools as the temperature decreases.
What is the relation between density, volume, and temperature?The density of the substance has been defined as the place occupied by the substance in a liter or milliliter of solution. It has been known to show an inverse relationship between volume and temperature.
As the liquid water cools down its temperature starts decreasing which causes the collision of the particles and kinetic energy to decrease leading to decrease in the volume of the matter as particles start moving close to each other.
As a result, the volume of the substance gets decreases which inversely affects the density of the material. The decreased volume increases the density of the substance. Hence, density shows an opposite reaction to the factors like temperature and volume.
Therefore, an increase in density is due to a decrease in the volume of the matter.

Diffusion is an example of
a) passive transport
b) phagocytosis
c) endocytosis
d) active transport
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.
Is DNP and cyanide an inhibitor of cellular respiration?
Answer: Yes.
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.
Pollen grains are formed in the anther of the flower by which sequence of events?Haploid microspore mother cells divide by mitosis to form four diploid microspores. Each microspore develops into a pollen grain by meiosis. Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis. Diploid megaspore mother cells divide by mitosis to form four diploid megaspores. Each megaspore develops into a pollen gram by meiosis. Diploid microspore mother cells divide by mitosis to form four haploid microspores. Each microspore develops into a pollen grain by meiosis. Haploid microspore mother cells divide by meiosis to form four diploid microspores. Each microspore develops into a pollen grain by mitosis.
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.
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane-bound carrier proteins is called The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane-bound carrier proteins is called
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.
Which objective is referred to as the "scanning objective"?
Answer:
This question lacks options; they are:
a. 4x b. 10x c. 20x d. 100x
The answer is A
Explanation:
The objective lens is an integral part of a light microscope as it provides the viewer with the picture or image of the specimen. There are several types of objective lens depending on their magnification.
The lowest possible objective lens with the power of 4x is called the SCANNING OBJECTIVE. In combination with the eye/occular lens, it provides a magnification of 4x × 10 = 40x. The name of this lens comes from the fact that it provides a full scan of every part of the specimen being viewed before diversifying into a specific region by changing the objective.
Mitochondria differ from chloroplasts in that Group of answer choices mitochondria convert solar energy to chemical energy whereas chloroplasts convert one form of chemical energy to another mitochondria contain three different membrane-bound compartments, whereas chloroplasts contain two mitochondria contain membrane folds called cristae, whereas chloroplasts contain vesicles in stacks called grana mitochondria are not found in plants, whereas chloroplasts are not found in animals
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.

Nervous systemFrom the question, we are to determine the two divisions of the autonomic nervous system.
The nervous system is divided into two main parts, which are
Central nervous system.Peripheral nervous system.The central nervous system is made up of the brain and the spinal cord, while the peripheral nervous system is made up of the nerves and ganglia that lie outside of the brain and spinal cord.
The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
The autonomic nervous system is further divided into the sypathetic nervous system and the parasympathetic nervous system.
The sympathetic nervous system is for fight or flight responses, and
The parasympathetic nervous system is for rest and digest responses.
