Answer 1

Answer: C

Explanation:

speciation results iIn more species, therefore a greater biodiversity

Answer 2

Speciation results in an increase in overall biodiversity. The correct option is C.

What is speciation?

The process by which populations develop into different species is known as speciation.

In contrast to anagenesis, which refers to phyletic evolution within lineages, cladogenesis, the separation of lineages, was first described by the scientist Orator F. Cook in 1906.

Rivers change their courses, mountains rise, continents drift, organisms migrate, and what was once a continuous population is split into two or more smaller populations.

According to scientists, who believe that geographic isolation is a common method for the process of speciation to start.

The most frequent type of speciation, allopatric speciation, takes place when populations of a species become geographically isolated. Gene flow between populations stops when they are divided.

The amount of biodiversity as a whole rises as a result of speciation.

Thus, the correct option is C.

Answers

Answer:

c. ​railroads

Explanation:

A water carrier carries both people and goods using waterways or sea routes. One of the main competitor for the movement of grain, coal and ores that are bulk products are the railroads.The competitor exists because majority of the places where it is possible to reach by waterways are also accessible via railroads.For example, the grains can be moved from midwest to New Orleans by both means. Similarly, coal can also be transported by both ways, some of the states where coal is produced and transported by this route is West Virginia, Pennsylvania and Kentucky.

What happens during the G1 phase of the cell cycle? Group of answer choices chromosomes are separated cell division is completed DNA replication occurs the cell grows and prepares for DNA replication

Answers

Answer:

The correct answer is: the cell grows and prepares for DNA replication.

Explanation:

The cell cycle is a series of steps that the cell goes under to grow and function and to prepare for reproduction.

The cell cycle can be divided into two main categories: interphase and mitosis (cell division). The interphase consists of 3 phases: G1, S and G2.

G1 is the phase where the cell grows and prepares for DNA replication: the organelles are copied.

S is the phase where DNA replication occurs, to provide a DNA copy to each of the daughter cells that will be resulting from mitosis.

In G2, the cell grows more and make more proteins; its organelles are rearranged in order to prepare for mitosis.

Mitosis is where the chromosomes are separated and given to the daughter cells, that will be identical to the parent cell.

Final answer:

During the G1 phase of the cell cycle, the cell grows, performs its regular metabolic activities, and gears up for DNA replication. Chemical messengers regulate this process closely to ensure precise and orderly progression to the next phase. Malfunction in these mechanism can lead to uncontrolled cell division, potentially causing diseases like cancer.

Explanation:

The G1 phase, or first gap phase, is the initial stage of the cell cycle. During this phase, a cell grows, carries out normal metabolic functions and processes, and prepares for DNA replication. This phase essentially sets the stage for the DNA to replicate in the subsequent S phase (Synthesis phase). The cell actively accumulates the building blocks of chromosomal DNA and proteins, along with amassing sufficient energy reserves to facilitate the process of duplicating each chromosome.

Chemical messengers inside and outside the cell carefully regulate this part of the cell cycle, providing the necessary signals for progression from one phase to the next. Failure in these signals could potentially lead to uncontrolled cell division, a condition implicated in cancer. Thus, the G1 phase is a crucial part of the cell cycle, setting the groundwork for the stages that follow and ensuring that cell division happens accurately and orderly.

Explanation:

Fat-solvent vitamins are put away in the body's greasy tissue. The four fat-dissolvable vitamins are vitamins A, D, E, and K. These vitamins are ingested all the more effectively by the body within the sight of dietary fat.  Vitamin A helps frame and keep up solid teeth, bones, delicate tissue, mucous films, and skin.  Vitamin D is otherwise called the "daylight vitamin," since it is made by the body subsequent to being in the sun. Ten to 15 minutes of daylight 3 times each week is sufficient to deliver the body's prerequisite of vitamin D for a great many people all things considered scopes. Vitamin E is a cancer prevention agent otherwise called tocopherol. It enables the body to frame red platelets and use vitamin K.  Vitamin K is required in light of the fact that without it, blood would not stay together (coagulate). A few investigations propose that it is significant for bone.Hence, the right answer is option c "vitamin A,D,E and K"

Answer:

The right and left subclavian vein.

Explanation:

It is known that lymphatic vessels flushes the tissues, collecting waste products, bacteria, and damaged cells, and then drains as lymph into "left and right subclavian vein".

Lymphatic vessels begin in peripheral tissues and ultimately drain into the lymph nodes.

What are lymphatic vessels ?

The lymphatic system is a network of vessels that transports lymph, a clear fluid that contains white blood cells. Lymphatic vessels are found throughout the body, and they transport lymph from the tissues back to the bloodstream.

Lymphatic vessels begin as lymph capillaries in the tissues. Lymph capillaries are very small, and they have very thin walls. This allows lymph to flow easily into the capillaries.

Once lymph enters the lymphatic capillaries, it flows through a network of larger lymphatic vessels. These vessels eventually drain into lymph nodes.

The targets for anti-fungal drugs are much more limited than antibiotics or anti-viral medications. Why?

Answers

Answer:The reason for this is because fungi and their host are eukaryotic and in treatment of fungal infections drug used can also affect their host.

Explanation:

Antifungal drugs are drugs used in the treatment of fungal infections and so are antibiotics and antiviral drugs used to treat bacterial infections and viral infections respectively.

Fungi and their host are both eukaryotic and this make them closely related. They attack by colonizing and destroying the tissues of the animal host. When treating infections caused by fungi, the compounds used to kill fungi also harm the animal host because of the eukaryotic property they both possessed, this therefore set limitations to antifungal drugs. Unlike fungi, bacteria attack prokaryotic cell and also bacterial infections are systematic not superficial or topical like fungal infections.
