B)It is based on the fact that genetic mutations although random, occur at a relatively constant rate. Evolutionary biologists use this information to deduce how species evolve and determine when two species diverged on the evolutionary time line.
It is useful in the study of variations in selective forces.
It also facilitates establishing the dates of phylogenetic events including those not documented by fossils.
The molecular clock technique is an important tool in molecular systematics. It helps to determine the correct scientific classification of organisms by deriving information from molecular genetics.

Hope this helped :) please mark brainliest

Answer:

A) A molecular clock is a measure of evolutionary time based on the theory that specific DNA sequences mutate at constant rates. To use a molecular clock, scientists first select two different species and compare their DNA sequences. They can compare the DNA sequences directly, or by looking at the RNA and protein molecules created from the DNA. Molecular clocks help to measure the number of changes and mutations which accumulate in the gene sequence of different species over a period of time.

B) Molecular clocks assume the neutrality of gene mutation. They are based on the fact that genetic mutations although random, occur at a relatively constant rate. Evolutionary biologists use this information to deduce how species evolve and determine when two species diverged on the evolutionary time line. It is useful in the study of variations in selective forces, and also facilitates establishing the dates of phylogenetic events including those not documented by fossils. Molecular clocks do have some limitations. Rates of change may not be constant, may not be the same in all organisms, and may be different for different genes.

I used the answer above and added some stuff here and there, so credit to them. I'm not sure if what I wrote makes much sense, but hopefully it can be somewhat helpful. :)


21. A soft sedimentary rock, like limestone, can change over time into a hard metamorphic rock
like marble. What processes must have acted on the limestone over the years to change this
sedimentary material into hard metamorphic material?

Answers

Answer:

The heat generated by the magma chamber has changed these sedimentary rocks into the metamorphic rocks marble, quartzite, an hornfels. Regional Metamorphism occurs over a much larger area. This metamorphism produces rocks such as gneiss and schist. ... They are generally as hard and sometimes harder than igneous rocks.

If sedimentary rock, pressed inside the crust and treated with a high pressure and temperature, then it can change over time into a hard metamorphic rock.

What is a sedimentary rock?

A sedimentary rock is mad up by the decomposition of minerals and other organic matter near the water surface.

These rocks are soft, such as limestone.

These rocks can turn into hard metamorphic rocks if they came in contact with high pressure and temperature.

Thus, by high pressure and temperature, the sedimentary rock change into hard metamorphic rock.

The process of meiosis is essential in the sexual reproduction and life cycle of many organisms. The outcome of meiosis is haploid gametes. Which statements correctly describe the importance of meiosis to the life cycle or these organisms?
A) Increasing genetic diversity ensures that no two haploid gametes are exactly the same.
B) Taking a diploid cell to its haploid state occurs during the first cell division of meiosis.
C) Checkpoints during meiosis ensures that chromosome separation occurs accurately, avoiding non-disjunction.
D) DNA synthesis occurs before each cell division in meiosis ensures that the integrity of the chromosomes is maintained.
E) Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization.

Answers

Answer:

E) Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization.

A) Increasing genetic diversity ensures that no two haploid gametes are exactly the same.

Explanation:

Meiosis is a kind of cell division that strictly occurs in sexually-reproducing organisms. It is the process whereby four daughter cells that are genetically different from their parents are produced. In meiosis, the chromosome number of each daughter cell (gamete) is reduced by half. As highlighted in this question, the meiotic process is essential in the sexual reproduction and life cycle of many organisms.

This importance is attributed to the fact that:

- Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization. That is, a diploid organism (2n) produces a haploid gamete (n), which becomes diploid again when fertilized by another gamete.

- Increasing genetic diversity ensures that no two haploid gametes are exactly the same. This occurs because of a process called CROSSING OVER, which enables that the alleles of each gamete is recombined to be different from one another in order to promote genetic diversity.

Can anyone help me with my homework

Answers

Answer:

Explanation: 1. Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

2.  Organic, Clastic and Chemical Sedimentary Rocks.

3. The formation of coal takes millions of years, which is why it is an exhaustible and non-renewable natural resource.

It was formed around 300 million years ago when the earth was covered with swampy forests.

When plants in these forests- mainly trees, mosses, ferns, and reeds died, they fell into the swamps.

Thus there was a thick layer of dead vegetation in the swamp formed.

4. Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering.

6.Squeezed and compressed over time, the sediments become 'consolidated' (made solid) into layers of rock. Stratigraphy is the study of those layers Cementation occurs when dissolved mineral components deposit in the interstices of sediments. It is the sticking together of sediment that forms a rock.

7. It is used by marine biota to form a shell frame. Shells of marine animals are rich in carbonate minerals. When the marine animals die, the shells will accumulate and settle in a place so that rocks are formed.

8. This may be due to the overburden load, which is essentially the weight of all the material above the layer of minerals in question squashing them flat. Or it may be due to deformation caused by the movements of tectonic plates which often causes a form of deformation known as shearing where two things slide past each other. When this occurs in ductile rock masses, it acts to flatten and rotate mineral grains so that their long axis is parallel to the shear plane.

B. Logistic growth
O C. Population crisis
O D. Population crash
SUBMIT

Answers

Answer:

A

Explanation:

When the population is well below the carrying capacity, it results into Logistic Growth.

What is Logistic Growth?

As competition increases and resources become increasingly scarce, populations reach their carrying capacity causing growth rate to slow nearly to zero.

This produces an S-shaped curve of population growth known as the Logistic Curve.

What are the factors determining Carrying Capacity?

Resources important for the survival of the species can act as a factor for Carrying Capacity .Example- For plants , it is water, sunlight, nutrients and space and for Animals- Food, Water, Shelter and Nesting Space.

Limited quantities of these resources results in competition between members of the same population or Intraspecific competition.

Examples of Logistic Growth are:

Yeast - A microscopic fungus can produce S shaped curve when grown in test tube.

Logistic Growth takes place when population's per capita growth rate decreases as population size approaches a maximum imposed by limited resources i.e. the carrying capacity.

Ecologists uses different methodologies for modelling Population Dynamics, amongst which major ones are Exponential Growth and Logistic Growth.

When the per capita rate of increase takes the same positive value regardless of the population size, it results into Exponential Growth whereas the per capita rate of increase decreases as the population increases towards a maximum limit, then we get Logistic Growth.

Why aren't there many large carnivores?

Answers

Answer:

Technically, the largest ever marine predator known thus far - the blue whale - is, for now, alive and well, but I know what you mean. You’re not talking about filter-feeders, or fish-eaters, you mean macropredators.

The last truly enormous macropredator in our oceans was probably Carcharocles megalodon, which went extinct about 3.6 million years ago. Other recent examples include the terrifying sperm whale Livyatan melvillei (which disappeared 8.9 mya) and other megatoothed sharks like C. chubutensis.

So, why did the giants go away? The answer, in truth, is likely multi-faceted. Here are some major promising hypotheses, or at least contributing factors:

Whales have declined. Giant sea carnivores like C. megalodon and Livyatan relied on marine mammals - specifically baleen whales. During the Pliocene, the Americas connected and the Central American Seaway was closed. This seems to have triggered a significant decline in the diversity of tropical whales, and would thus limit food availability for huge, energy-hungry predators.

Things got too cold. The extinction of megalodon and other giant ocean predators roughly coincides with the trend of decreasing temperatures the Pliocene brought. Giant sharks in particular, not being fully warm-blooded, would suffer from this, and it would also mean a decline in food supply. You can even see a sudden cold snap just about when Carcharocles went extinct, 3.6 mya.

Smaller predators outcompeted them. The niche of Carcharocles and the macroraptorial sperm whales is arguably still filled today - by the killer whale. Many orca pods specialize in hunting whales or other marine mammals. However, killer whales and their ancestors were perhaps more opportunistic, fast, intelligent and indeed adaptable than the massive, solitary hunters.

Ironically, the largest ever marine predator owes its existence to the demise of the largest ever marine macropredators. Since the extinction of macroraptorial sperm whales and Carcharocles megalodon, baleen whales have been gradually increasing in size, for they no longer need to be as fast and agile. Because of this, we have the privilege of sharing our world with the largest animal known to have ever lived - the blue whale.

Answer:

breaking down substances within the cell

Explanation:

there are many different types of vesicles, Peroxisomes and lysosomes are both types that break down substances in the cell

The correct statement about vesicles is "Breaking down substances within the cell"

Vesicles are an organelle isolated from the cytoplasm by a membrane-like lipid layer.

Its function is to store, move and process products and cellular waste.

Endocytosis and exocytosis transports are characterized by the fact that the substances move through vesicles.

The vesicles incorporate substances (endocytosis) and through degradation, they expel large particles that cannot cross the plasma membrane, this mechanism is exocytosis.

Therefore, we can conclude that the cell incorporates, inside the vesicle, particles from the extracellular environment and also through the vesicles it releases degradation products to the extracellular environment.
