What point in this body of water is most likely to have no plants growing
Answer:
Point D
Explanation:
Point D is the point that is most likely to not have any plants growing in it. The reason why this point of the body of water will not have any plants is because of the lack of light. This part of the body of water is dark, with no light penetrating to it. The plants need light to survive, as it is a vital element in the process of photosynthesis. If there isn't any light, the plants can not perform photosynthesis, thus they can not produce their own food, which in turn means that they will not exist in such a place.

A child has sickle-cell disease (ss) but neither parent is ill. What must be true of her parents’ genotypes? The father is heterozygous; the mother is normal. One parent has two recessive alleles. Both parents are heterozygous carriers. The mother is heterozygous; the father is normal.
Answer:
Both parents are heterozygous carriers.
Explanation:
Both parents are heterozygous carriers. Sickle Cell Anaemia is usually referred to as a recessive condition since an individual must have two copies of the sickle gene in order to have the disorder.
Since neither of the parents is ill, both of them must be heterozygous carriers for the child to have the disorder
Answer: Both parents are heterozygous carriers
Explanation:
Chicken pox is a virus that causes an itchy rash but typically does not have any major or lasting effects on an infected person. Before 1995, chicken pox parties were popular. In a chicken pox party, healthy children were brought around children who were sick with chicken pox so that they would be exposed to the virus and their immune system would learn to fight it. A vaccine for chicken pox was developed in 1995, and chicken pox parties are now rare. What best describes how vaccines have advanced science? Vaccines are more effective on ethnicities that are highly susceptible to a disease. Vaccines can determine which genes can cause disease. Vaccines can minimize lifestyle choices that allow for greater exposure to a disease. Vaccines allow for building immunity without harmful exposure because not all viruses are safe to be exposed to
Answer: yes
Explanation: well Chicken pox is a virus that causes an itchy rash but 1995

What's one cause of the heat island effect? A. Pollution of groundwater B. Reduced rainfall in urban areas C. Higher albedo in urban areas D. Lower albedo in urban areas
Answer:
D. Lower albedo in urban areas
Explanation:
The heat island effect is caused by several factors, but one of the most important ones is the low albedo. This is particularly the case in the large urban areas. The large urban areas have low albedo, meaning that the solar radiation is accumulated in greater extent, and less of it is reflected back to the atmosphere. This results in an increase of the surface temperature, and the lowest parts of the atmosphere above it. The reason why this happens is that the urban areas are dominated by materials that have low reflection of the solar radiation, such as the concrete and asphalt. The concrete and asphalt are actually absorbing the solar radiation, so the their temperatures is increasing, and since they are the dominant materials, most of the area has rise in the temperatures. In practice this can easily be noticed by the people, as if the weather is warmer, in larger urban area it feels like we are in an oven, with heat surrounding us from all sides.
Answer:
D. Lower albedo in urban areas

why would two different species have similar features or behaviors?
A.similar DNA
B.similar mutations
C.similar environmental pressures
B. similar mutations
Final answer:
Species can have similar features or behaviors if they face similar environmental pressures leading to convergent evolution or if they have a common evolutionary history indicated by homologous structures. Analogous structures can also occur when species evolve independently to have similar adaptations.
Explanation:
Two different species may have similar features or behaviors due to the convergence of form in organisms that share similar environments, a concept known as convergent evolution. For example, the arctic fox and ptarmigan both have seasonal white phenotypes to blend with the snow and ice. This occurs not due to a common ancestry, but because of similar environmental pressures that offer advantages such as camouflage from predators.
Another reason for similarities might be due to homologous structures, which are features that are similar in form and genetic makeup and indicate a close evolutionary relationship. An example of homologous structures is the similarity in bone structure of bat and bird wings. However, when similarities occur between species that aren't closely related, due to adapting to similar environmental challenges rather than common ancestry, these are referred to as analogous structures or homoplasy. Insect wings vs. bird and bat wings are an example of such analogous structures.

Which type of unconformity occurs when sedimentary rock overlies igneous rock?
Question 8 options:
disconformity
nonconformity
angular unconformity
conformity
Answer:
nonconformity
Explanation:
There are multiple types of unconformity that occur in nature, all of which are base on the relative position of the types of rocks. The nonconformity is one of the unconformities. This type of unconformity occurs when sedimentary rock overlies igneous or metamorphic rocks that existed there before the sedimentary rocks covered them. The nonconformity can be seen in lots of places around the world, but it is most common on places where there are water bodies like lakes, seas, oceans, ponds, marshes, or on places where there were water bodies of this type in the past.

1. Variations in a population of moths allow for some of its members to be able to adapt to environmental changes. The better adapted of the moths will be able to survive the change and thus prevail as the “fittest” of the species. (a) Describe three mechanisms in which variation can occur within a species population. (b) Explain which mechanism or mechanisms would be responsible for the survival of a population of peppered moths better than white moths in an environment affected by industrial soot. Justify your answer.
Answer:
a) mutation, mimicry and camouflage
b) During an industrial soot there would be black ashes throughout the environment, spotted moths blend in with the surroundings making them more difficult to spot then white moths. Therefore white moths are easier for predators to prey on.

Which could be a reason viruses are considered nonliving things? Viruses come from cells. Viruses produce cells. Viruses are made of DNA and proteins, but not cells. Viruses attack cells and are dangerous to them.
Answer: Option C
Explanation:
The reasons why the viruses are considered to be non living things are:
They contain DNA and proteins but they are not considered as cells this is because they do not perform any cellular machinery as they they do not have organelles.
They do need host to survive they cannot live independently in nature. They do not grow in size and cannot keep them in steady state.
They cannot perform metabolic reactions and cannot generate energy for the life processes.

Humoral—B lymphocytes; cell mediated—neutrophils
Humoral—T lymphocytes; cell mediated—neutrophils
Humoral—neutrophils; cell mediated—T lymphocytes
Answer:
B cells and T cells, respectively.
Explanation:
Humoral and cell-mediated immunity are parts of adaptive immunity, which is acquired by an individual in his lifetime due to exposure of pathogens. Cells involved in humoral immunity are B lymphocytes or B cells. These cells form antibodies to fight against infections.
Cells involved in cell-mediated immunity are T lymphocytes or T cells. These cells release various cytokines that activate other immune cells or kill pathogens directly.
Thus, the correct answers are B cells and T cells, respectively.

a. try a different experiment.
b. trust the second results.
c. decide which results are better.
d. repeat the experiment again.
Answer:
repeat the experiment again and if the third one matches with first one then first one is right and if it matches with second one than the second one is right
The experimental method is the involvement of the independent and dependent variables. The next step should be repeating the experiment again. Thus, option d is correct.
What is the experimental method?The experimental method has been the controlled method that involves the two groups that have been constituted of the variables that are controlled, dependent and independent. It tests the falsifiability of the hypothesis.
The experimental method must be performed again as there is a difference between the results of the experiment. So as to conclude the reliability and definitive findings of the experiment must be repeated again and must be cross-checked with the previous results.
Therefore, option d. the experiment must be repeated again.

What if biological profiles were created to identify individuals who were most likely to engage in criminal behavior? What would be the possible consequences of identifying believed criminals before they were actually criminal?
Answer:
the possible consequences of identifying believed criminals is by doing a back ground check
Creating biological profiles to identify potential criminals raises ethical issues and overlooks the social and environmental factors leading to crime. Sociologists reject biological explanations, focusing instead on socio-environmental factors for understanding crime patterns.
The student's question concerns the potential consequences of creating biological profiles to preemptively identify individuals who might be more likely to engage in criminal behavior. It is essential to recognize that sociologists generally oppose relying on individual biology or psychology to explain criminal behavior, as these theories fail to account for the social patterning of crime seen across different locations and demographics.
Biological profiles and identifying potential criminals based on genetic predisposition could lead to significant ethical and social issues, including discrimination and violations of individual privacy. Genetic markers cannot reveal the complex interplay of social, environmental, and individual factors that lead to criminal behavior. Moreover, profiling based on biological traits could reinforce existing prejudices and stereotypes associated with gender, race, ethnicity, social class, and more.
It's important to recognize that such biological theories once held sway but today are considered inadequate in explaining criminal behavior. The focus has shifted to socio-environmental factors that contribute to crime, which suggest that targeted interventions and inclusive social policies are more effective in reducing crime than profiling based on biology.

Through which structure do wastes pass into the rectuin?
a. large intestine
b. villus
c. small intestine
d. duodenum
Answer:
A. Large intestine
Explanation:
This is because that's how the body works lol :)
Through large intestine waste is passed into the rectum.
Explanation:
In the digestive system the digested food material present in the stomach travels gradually from the duodenum to the small intestine where it splits into small molecules.
Whereas, absorption of those food material takes place through the small finger like structures present in the small intestine known as villi (singular-villus). After small intestine the food enters into large intestine where it reaches to the rectum to be excreted as waste.
If a cell has the ability to take in water, food molecules, and other necessary materials this indicates it is capable of... A: Biosynthesis B: Nutrition C: Absorption D: Digestion
Answer: C: Absorption
Explanation:
The absorption is a process of direct intake of water and nutrients in the form of simple molecules by the body of the organisms. These materials are retained within the body and converted into forms of energy which can be utilized for the purpose of cellular metabolism and performing various physical functions.
