Answer:

rate of division

Explanation:

In normal cells, the cell cycle is controlled by a complex series of signaling pathways by which a cell grows, replicates its DNA and divides. In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation.

HOPE IT HELPS :)

PLEASE MARK IT TH BRAINLIEST!

Cancer is a disease in which some cells lose their ability to control rate of division. The correct option is C.

Cancer is the body's unchecked proliferation of aberrant cells. When the body's natural control system malfunctions, cancer might emerge.

Instead of dying, old cells proliferate uncontrollably to produce new, aberrant cells. These excess cells could aggregate into a tissue mass known as a tumour.

Genes, the fundamental building blocks of inheritance, can change in ways that result in cancer.

Chromosomes are long, tightly packed DNA strands where genes are organised. Since genes that determine how our cells behave, particularly how they grow and divide, are altered, cancer is a genetic disease.

Thus, the correct option is C.

Answer:

The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.[

Explanation:

The weathered material of a sandstone outcrop revealing an abundance of feldspar and quartz grains would have come from a granite outcrop up the road rather than a nearby basaltic lava flow.

Feldspar is a common mineral found in granite, whereas it is less abundant or absent in basaltic lava flows. Granite is composed primarily of feldspar along with quartz and other minerals. So, the presence of an abundance of feldspar grains suggests a connection to granite rather than basalt.

Quartz is present in both granite and basalt, but it is more commonly associated with granite. Quartz is one of the major constituents of granite, whereas it is generally less abundant in basaltic lava flows. Therefore, the presence of quartz grains does not necessarily differentiate between the two sources but aligns more with the possibility of granite as the origin.

Answer: Valid Statement ✓

Explanation:

Bats have been known to contribute to the growth and restoration of Tropical Rainforests in 2 main ways. Seed Dispersal and Pollination.

Seed Dispersal.

Fruit Bats in the Tropical Rainforest are responsible for a lot of seed dispersal. Feeding at night to avoid predators, they eat fruits from various trees and then defecate these seeds after digestion. Fruit Bats like most other bats are very strong fliers and so cover a whole lot of distance at night meaning that they give the seeds a very wide coverage. Indeed it has been shown that because they defecate the seeds, the seed already has fertilizer to get nutrients from as it grows thereby increasing it's growth rate.

There are also trees and plants that have evolved to grow spiky or sticky fruit that attach themselves to the Bats which then deposit them elsewhere as they fly.

Pollination.

Fruit Bats have specialized long tongues to sip nectar from flowers. When they do this they pollinate the flowers. It has even been shown that some plants evolved to have brighter colours so as to attract these bats to enable pollination to happen. Indeed research shows that more than 125 genera of tropical plants rely on bats for pollination.

Bats plays an essential role in the existence of rainforests, they help to replenish and expand the area of rainforests.

Bats plays an essential function in the existence of rainforests. Along with the birds they assist in some of the major activities like replenishing the devastated region and expanding the region of rainforests. It is known that the majority of the tropical plants are dependent upon the methods of seed dispersal for expansion of rainforests.

Apart from this, restoration of rainforests is also dependent upon the fruit-consuming animals like bats. Bats helps to disperse the shrub species to the gradually regenerating barren landscapes or grasslands or rainforests, which got devastated. It has been found that about 90 percent of the pollination and dispersal of seeds in rainforests is done with the help of species like bats.

The bats can assist in regenerating the deforested areas in short span of time in comparison to any modern strategies. Therefore, bats helps in afforestation of rainforests. Due to their aerial nature, they possesses the tendency to cover wide region and plays significant role in dispersal and pollination.

Thus, bats are essential for the existence of rainforests.

In this lecture you learned that due to evolutionary descent, organisms share many of the same genes and proteins. However, distantly related organisms have more DNA differences than closely related organisms.

Organic evolution general refers to the descents, with modification, of organisms from common ancestors. Hence, organisms that share the same ancestors share several similar genes and proteins due to their common lineage. The closer the organisms, the more similar their genes and proteins, and the distant the organisms, the more dissimilar their genes.

Answer:

Its Eurasian

Explanation:

This boundary is between the African Plate and the Eurasian Plate.

This boundary is known as a convergent plate boundary. Convergent plate boundaries occur when two tectonic plates move toward each other.

In the case of the African Plate and the Eurasian Plate, they are colliding, and one plate is being forced beneath the other in a process called subduction.

As the plates converge, the intense pressure and friction cause seismic activity, leading to earthquakes and volcanic eruptions in the region.

These collisions also result in the formation of mountain ranges, such as the Himalayas, as the crust is pushed upward and folded.

Studying this convergent plate boundary is essential for understanding the geological processes shaping our planet's surface and the associated hazards like earthquakes and volcanoes.

Explanation:

If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have

2 possible gametes for each five = 2 to the power of 5 = 32 gametes

Then genotypes = 3 to the power of 5 = 243

The same also for 10 genes

2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

Then genotypes = 3 to the power of 10 = 59,049

The same also for 20 genes

2 possible gametes for each 20 = 2 to the power of 20= 1,048,576

Them genotypes = 3 to the power of 20 = 3,486,784,401

Many traits (phenotypes), like eye color, are controlled by multiple genes. In the following scenario, the number of genes are:

a. 5 Genes: 243 genes

b. 10 Genes: 59,049 genes

c. 20 Genes: 3,486,784,401 genes

Genes are small hereditary materials bound in tiny beads like fashion and make a chromosome.

Now, the number of genes in the given scenario is:

a. 5 Genes: If there are 5 genes, let us assume that they are in the alternative forms, with 2 possible gets for each five.

So, 2 possible gametes for each five = 2 to the power of 5 = 32 gametes

The genotypes combinations = 3 to the power of 5 = 243

b. 10 Genes: 2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

The genotypes combinations = 3 to the power of 10 = 59,049

c. 20 Genes: 2 possible gametes for each 20 = 2 to the power of 20 = 1,048,576

The genotypes combinations = 3 to the power of 20 = 3,486,784,401

Answer:

Enzymes and substrates fit together like a lock and key since, in one enzymatic reaction, only the correct substrate (i.e., the key) binds to its corresponding enzyme (i.e. the lock).  

Explanation:

An enzyme (or catalyst) is one protein that has catalytic functions, being therefore capable of accelerating chemical reactions. The enzymes are known to control the rate of these chemical reactions (i.e., catalysis) without suffering alterations during these processes. Thus, the enzymes are proteins that catalyze chemical reactions that are not favored under normal conditions. Moreover, one enzyme may catalyze more than one chemical transformation, as well as the same reaction may be catalyzed by two or more enzymes.

Answer:

The ATPs produced during Chemeiosmosis, in the chloroplast is needed during Calvin cycle to fix carbon for production of CHO, protein and fats  during conversion of 3C-glyceride phosphate(GP) to 2C- triose phosphate.(TP) .

The ATPs is needed for this reduction to take place in the presence of NADPH(which is oxdized to NADP).

Therefore, if the final electron acceptor is removed, there will be no electron transport chains which generated the PMF, for pumping H+ across into the thylakoid membrane of the chloroplast, to generate the electrochemical gradients, needed for  the energy for ATPase synthase enzymes,to synthesize ATPs production.

Therefore, the removal of the electron acceptor (oxygen) leads to stoppage of electron transport chain, and hence loss of ATP s, and therefore, no Carbon fixation as CHO, or protein, or fats.

Answer: 6) sodium channel activation occurs.

4)a graded depolarization brings an area of excitable membrane to the threshold.

7) sodium ions enter the cell and further depolarization occurs.

1)sodium channels are inactivated.

2) voltage-regulated potassium channels open and potassium moves out of the cell, initiating repolarization.

3) sodium channels regain their normal properties.

5) a temporary hyperpolarization occurs

Explanation:

action potential occurs when the differences in the concentrations of ions on opposite sides of a cellular membrane lead to a voltage of a specific cell location rapidly rises and falls.

The steps involved in this generation are;

First of all the sodium-gated channel activation occurs due to inflow of Na, this is called depolarization. A graded depolarization brings an area of excitable membrane to the threshold. More sodium ions enter the cell and further depolarization occurs. After which the sodium channels are inactivated due to the opening of voltage-regulated potassium channels and potassium moves out of the cell, returning it to it initial resting phase initiating repolarization. sodium channels regain their normal properties. a temporary hyperpolarization occurs which is a transient negative shift after an action potential occurs.
