Can someone please check my answers :))

Thank you <<3

Answer: I had the same problem in one of my exams. I think the answer is "the ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought.

Explanation:

I chose this because it seems like the most logical explanation.

"The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.

Biodiversity is considered as the variety of living things found in the various habitats, such as terrestrial, marine, and desert ones, as well as the ecological groups to which they belong.

The variety of the creatures present in an ecosystem, as well as their relative abundances, is referred to as biodiversity. It also depicts the various stages of organism organization.

In ecosystem there are thirteen different grass species present and in ecosystem Y 1 species of grass present, that is,  ecosystem X has a greater amount of biodiversity. So, during  the drought, the bison in ecosystem X are better able to survive.

Therefore, "The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.

Explanation:

Answer:

ice is a solid.When heat is added it turns into a liquid,its a reversible change.As regarding to the water moleculesWhen water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)

Answer:

C) exponential growth​

In the given figure, exponential growth curve is pictured.

It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:

In the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.

In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.

Thus, the pattern of growth demonstrated in the given figure is exponential growth.

Answer:

Photosynthesis

Explanation:

Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Answer:

[tex]\boxed {\boxed {\sf Glucose}}[/tex]

Explanation:

Plants (plus some bacteria and algae) are autotrophs and undergo a process called photosynthesis.

They obtain light energy from the sun and capture it using a green pigment called chlorophyll, water from the soil is drawn up through the roots with capillary action, and carbon dioxide diffuses into stoma on leaves.

Then, in the chloroplast, these substances are turned into oxygen and glucose. Both of these are used in cellular respiration, which creates energy for the plant to grow and carry out cellular and biological functions. Therefore, glucose is often called "food" for the plant.

Answer:

Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.

Surface currents are created by three things:

global wind patterns

the rotation of the Earth

the shape of the ocean basins

Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.

Answer:

The Coriolis effect causes winds and currents to form circular patterns.

Answer:

sickle cell anemia and malaria

Explanation:

Scientists believe the sickle cell gene appeared and disappeared in the population several times, but became permanently established after a particularly vicious form of malaria jumped from animals to humans in Asia, the Middle East, and Africa.

The two diseases have been studied together that provide evidence of evolution in humans is sickle cell anemia and malaria.

The sickle cell mutation is relevant to malaria because infection of a red blood cell with the malaria parasite leads to hypoxia. In individuals of the AS genotype such blood cells sickle and are then eliminated by macrophage cells of the body’s immune system, lessening the burden of infection (Luzzatto, 2012). Carriers of the sickle cell trait are particularly resistant to severe malarial episodes; they are less resistant to mild cases. The mechanism by which carriers are protected from malaria is different than the acquired immunity that both AA and AS individuals achieve following repeated exposure to the disease.

The benefit that possessing a single copy of the sickle cell gene conveys counterbalances the biological cost incurred when homozygous SS children are stricken with sickle cell disease. An individual of the AS genotype is more likely to reach adulthood than is an individual of the AA genotype, but the former is also more likely to see his/her child die of sickle cell disease. This is known as a heterozygote advantage or balanced polymorphism. As shown more formally below, the stronger is the pressure of malaria on survival, the more advantaged are individuals who carry the S gene, and in equilibrium, the higher the percentage of the population who will be carriers. Indeed, it was the correlation of high prevalence of the sickle cell gene and the presence of malaria that first led scientists to understand the protective role of the sickle cell mutation (Kwaitkowski, 2005). As will be seen in the next section, the underlying genetic mechanism by which the sickle cell trait is transmitted provides a means of mapping sickle cell prevalence into an estimate of the mortality burden of malaria.

Answer:

c increases genetic diversity

Explanation:

Answer:

C. increases genetic diversity

Explanation:

First, by process of elimination: sexual production doesn't necessarily increase survival rate, it can, but not always. Sexual reproduction involves two parents, so b is wrong. And sexual reproduction doesn't produce identical offspring, because it's mixing the genes from both parents, do d is wrong. That only leaves c, with two parents, the gene pool is always expanding, and with less chance of mutation

Answer:

Explanation: Não sei

Answer: B

the traits for white fur and red eyes were always inherited together.

Explanation:

The hypothesis would not have been supported by the data if the traits for white fur and red eyes were always inherited together by the law of independent Assortment.

So we can conclude that as the qualities for white fur and red eyes are not usually inherited together, we may deduce that the two features are regulated by distinct genes and are independently shown in the person, as stated by the law of independent Assortment.

Explanation:

Answer:

The high sugar content caused too much water to move out of the root cells.

Explanation:

Too much causes transpiration to occur, in this case too much water killed the plant.

The statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.

High sugar content in plants may be defined as the amount of carbohydrates (glucose) and their components get accumulated in the different parts of the plants in a high ratio. It also affects the rate of photosynthesis.

High sugar content leads to the loss of water (transpiration) in plants. In this condition, water loss is maximum which results in the scarcity of water in the root cells. And hence the plant died.

Therefore, the statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.

Answer:

D

an increase in the length of the fatty acid tails.

Explanation:

As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated

and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and

decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and

more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity

Answer:

Index of refraction is the ratio of the velocity of light in medium to the velocity of light in vacuum.

OR:

Index of refraction is the ratio of the sine of the angle of incidence to sine of the angle of refraction of light propagating from one medium to another.

When the refractive index is greater, the speed of light is greater as it moves from the medium to vacuum.
