Answer:
B. preservation of advantageous genetic mutations
Explanation:
The process of natural selection involves the preservation of advantageous genetic mutation in a given population.
Natural selection is one of the key factors that ensures the evolution of organisms.
Desired traits that are able to survive adverse conditions like disease, food shortage, natural disasters are favored by the process of natural selection. Traits that also undergo advantageous genetic mutation in order to get a competitive advantage is also accrued to natural selection.Which best describes how wedge basins form?

Choose the mutation that you think is causing Lucy’s ADA enzyme not to work.
Form a hypothesis and explain your answer.
You can revise your hypothesis as you perform more experiments.
Answer:
Stop Codon Mutation
The mutation that I think that is causing Lucy's ADA enzyme to not work is stop codon mutation. I think so because the stop codon mutation shortens the amino acid sequence causing Lucy to have a lower amount than normal.
Explanation:
I just did it
The mutation that causes Lucy's ADA enzyme not to work is a nonsense mutation.
What do you mean by Mutation?
The sudden, stable, and inheritable changes in the genetic material of an individual, are known as Mutation.
A nonsense mutation or stop codon mutations end the process of protein synthesis. Because these codons do not code for any amino acids. Thus, nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence.
Therefore, the mutation that causes Lucy's ADA enzyme not to work is a nonsense mutation.

Which animals should not be vaccinated?
Answer:
Every dog and cat should be appropriately immunised, and each individual animal should be vaccinated as frequently as considered necessary by their veterinarian to provide protection. The vaccination protocol to be followed and the vaccines to be used should be determined within a veterinarian–client–patient relationship. The decision should be determined by factors such as the individual animal’s health status, the animal’s age and likely effects of maternally derived antibodies (MDA), the particular disease and environmental risks to the animal, and the duration of immunity (DOI) of available vaccines.
Meditation is a practice of sitting still and quiet for minutes or even hours. It has been practiced for thousands of years and is even a part of religious practices for some people. Carefully controlled, repeated measurements of brain activity have shown that meditation does increase certain chemicals in the brain and even grows the part of the brain that helps people connect with their current surroundings and activities.
Are claims about the effects of meditation most likely scientific or pseudoscientific?
(Answer:) this is most likely to be scientific, (Explanation:) because, if you look at the question it says 'are the effects of medditadion scientific?... ect', and if you look back on your description of meditation, in the third sentence, they certainly state information based on scientific study!
Answer:
scientificExplanation:, because observations of brain growth and chemicals are made carefully and repeatedly

Minerals are rarely used in everyday life true or false
Answer: False
Reason: We Use Minerals In our day to day life, when it comes to cooking, or burning. We use Salt to cook amazing meals, and some pots and pans have minerals built in to them so that they last longer over the years you cook with them. When we burn in the fireplace or in the backyard, some of us use coal and light it up, and sometimes, we use minerals to make buildings. In one of my neighboring towns, their City Hall has little mineral pieces built into the City Hall. I hope this helps, and happy holidays! :)

How are precipitation and temperature different between the polar and tropical climate zones?
Answer:
The temperature is colder in the polar climate zones. Also, there is less precipitation in polar climate zones. Meanwhile,the temperature is warmer in the tropical climate zones. Also, there is more precipitation in tropical climate zones.
Explanation:
The earth is extremely diverse in its ecosystem. Different regions are called climate biomes to understand patterns of meteorology, biology, and natural phenomena.
The biggest difference between tropical and polar climates is the difference in temperature. The tropical climate is close to the equator and has more sun all year round than anywhere else on the planet, but the polar climate is the furthest from the equator and has the least sunlight and heat of any part of the world. This makes winters harsher and summers shorter in polar climates, but hotter virtually every day in tropical climates. Both climates are reminiscent of precipitation (such as tropical rains and polar snow), but both can be quite dry. Antarctica is said to be the largest desert in the world because there is little snow falling towards the center of the continent.
What are examples of tropical desserts?Tropical deserts, such as the Namib Desert in Africa, are so hot and dry that it is difficult to survive.
Thus it concludes that precipitation and temperature are different between the polar and tropical climate zones.

1. Other than having many features in common, state other characteristics of species 2. Give reasons for the loss of energy from one trophic level to the next in a food chain.
Answer:
As a metabolic heat.
Explanation:
The loss of energy from one trophic level to the next in a food chain occurs because energy is lost in the form of heat when the organisms from one trophic level are consumed by organisms from the next level. Only 10% of energy is transferred from one trophic level to another while the remaining 90% energy is lost in the form of heat energy in the ecosystem.

Are catabolic pathways endergonic or exergonic reactions? Compare the amount of free energy in the reactants to the amount of free energy in the products of a catabolic pathway.
Answer:
Catabolic reactions are exergonic.
Explanation:
Exothermic reactions are catabolic, that is, they catalyze molecules, disintegrate them to be able to release energy to the environment that surrounds them and that is how they release or yield to the environment.

A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?
Answer:
0.2Hz
Explanation:
The wavelength of a radiowave can be calculated this;
λ = v/f
Where;
λ = Wavelength (m)
v = speed (m/s)
f = frequency (Hz)
Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?
Hence, using λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 1.5 x 10^9
f = 2 × 10^(8-9)
f = 2 × 10^-1
f = 0.2Hz

Answer:
Allow carbon to enter an ecosystem through photosynthesis
Explanation:
Though plants are known to sustain life through the process of photosynthesis. In this process plants simply takes in carbon dioxide and releases oxygen.
However, this is a type of process is considered to be active during the day, while at night plants absorb oxygen and release carbon dioxide
Hence, Plants play a crucial role in the carbon cycle because they "Allow carbon to enter an ecosystem through photosynthesis."
