Within a plant cell, the glucose formed as a result of
photosynthesis may be used directly as
1) an energy source during cellular respiration
2) an enzyme for intracellular digestion
3) an absorber of radiant energy
4) a source of molecular oxygen

Answer:

The right answer is B. Glucose molecules will diffuse out of the cell

Explanation:

Diffusion refers to the natural tendency of a system to homogenize the concentrations of chemical species within it.

Answer:

The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone.

Answer:

proximal tubule

Explanation:

Glucose reabsorption takes place in the proximal tubule of the nephron, a tube leading out of Bowman's capsule. The cells that line the proximal tubule recapture valuable molecules, including glucose.Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule.

Complete question:

True or False: The reason that the nail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis.

Answer:

False

Explanation:

Nails are composed of the lamina, which is a smooth, shiny, translucent, and keratinized structure. The nails are born the nail matrix. The newly formed nail slice along the mail bed, which is the plane surface under the nails.  

The nail bed places under the nail and is composed of a thin epithelium, with no granulous stratum, and a few layers of parakeratotic cells attached to the nail.  

The nail matrix and nail bed have melanocytes. Half of the melanocytes of the matrix produce melanin, while melanocytes of the nail bed are inactive.  

The nail bed is laying over many small vessels that nourish it and provides a pink color to the nails.

Answer:

The biology branch deals with the relations between and physical environment of organisms.

Explanation:

The principle of competitive exclusion states that if two species occupy the same niche, they cannot exist together (competing for identical resources). Two species whose niche overlap can evolve to have different niches through natural selection, resulting in the distribution of resources.

In ecology, interspecific competition is a form of competition where individuals from different kinds compete in an ecosystem for the same resources (e.g. food or space)... There may be interspecific competition if people of two separate species share a limited resource within a single area.

A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen.

The scanning electron microscope (SEM) produces images by scanning the sample with a high-energy beam of electrons. As the electrons interact with the sample, they produce secondary electrons, backscattered electrons, and characteristic X-rays.

The primary motivation for conservation and is to conserve wildlife and maintain biodiversity. Safeguarding wildlife and environment and conserving it for future generations ensures that the species we care about do not become extinct. The preservation of such ecosystems aids in the protection of the overall ecosystem.

Answer:

a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.

Explanation:

The occurrence of action potential requires the existence of active voltage-dependent channels to open and close in response to the membrane depolarization.  

When depolarization reaches and supers the threshold point, voltage-dependent Na+ channels open and the ion gets into the cell. The entrance of Na+ decreases the electric charge difference between the cellular interior and exterior. Membrane depolarizes and produces the action potential that tends to reach a potential equilibrium for Na+ = +60mV. The higher the Na+ input is, the greater is the depolarization and the greater is the Na+ permeability.

Once Na+ channels are closed, voltage-dependent K+ channels open, increasing the membrane permeability to the ion, letting K+ get out of the cell, following the electrochemical gradient.  

The closure of Na+ channels and opening of K+ channels are responsible for membrane repolarization.

DNA copying is otherwise known as DNA replication which is the process of producing 2 identical copies of DNA from one original DNA molecule during cell division. DNA copying is important because it generates variation during sexual reproduction which leads to evolution. Also, DNA copying helps in transfer of information or characters from the parents to the offsprings.

Mendel studied traits with only one mode of inheritance in pea plants. The inheritance of the traits he studied all followed the relatively simple pattern of dominant and recessive alleles for a single characteristic. There are several important modes of inheritance, discovered after Mendel’s work, that do not follow the dominant and recessive, single-gene model.

third world countries

Explanation:

Answer:

lichens, hearty shrubs, trees

Explanation:

Order:

I-bare rocks,

II-pioneers (mosses, lichen, algae, fungi)

III-annual herbaceous plants

IV-perennial herbaceous plants and grasses

V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.

(please mark me brainliest) :)

Lichens, hearty shrubs, and trees is the correct order in which the organisms return to an ecosystem during primary succession after an area's ecosystem has been wiped out. Thus, the correct option is C.

Primary succession is the ecological succession which begins in essentially the lifeless areas, such as the regions in which there is no soil or where the soil is incapable of sustaining life where no life form ever existed because of recent volcanic eruption, newly formed sand dunes, or rocks that are left from a retreating glaciers.

The correct order of the Primary Succession is:

Stage I- Bare rocks,

Stage II- Pioneer species such as mosses, lichen, algae, and fungi

Stage III- Annual herbaceous plants

Stage IV- Perennial herbaceous plants and grasses

Stage V- Shrubs, shade intolerant trees, and shade tolerant trees.

Therefore, the correct option is C.

These cats should be kept indoors and seen to by specialist veterinarians, as long term management of the condition is essential for quality of life in these cats.

Which situation do u mean?

Answer:

It is expected that each parent is homo-zygous for each trait (i.e., one parent has genotype AA and the other parent has genotype aa)

Explanation:

An F1 hybrid is the first filial generation of the progeny of distinctly different parental types. In this case, it is expected that each parent is homo-zygous for each trait, thereby 100% of all offspring will have genotype Aa (i.e., parental cross: AA x aa >> F1 = 100% Aa). On the other hand, in a cross where one parent is heterozygous for the trait (Aa) and the other parent is homo-zygous (either AA or aa), only 50% of all offspring will have genotype Aa.

Question doesn't see clearly than how to help

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.

=============================================

For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.

Recall that

distance = rate*time

we can rearrange things to say

rate = distance/time

So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.

----------

So,

rate = distance/time

rate = (260 meters)/(180 seconds)

rate = (260/180) meters per second

rate = 1.44 meters per second, which is approximate

I'm rounding to 3 sig figs.
