In a California kelp forest, the garibaldi, the purple sea urchins, and the rocks make up part of a community and part of an ecosystem. Therefore, option B and C are correct.
What is ecosystem ?All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue.
Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors.
Healthy ecosystems maintain our soil, clean our air, control the climate, recycle nutrients, and give us food. They offer resources and raw materials for making medications and other things. They support our economies and are the cornerstone of all civilizations.
Thus, option B and C are correct.

Is a beneficial mutation always
considered beneficial?
A. No, it depends on the organism's personal goals.
B. No, it depends on the organism's environment.
C. Yes, it will always increase the organism's chances of
survival.
D. Yes, it will always increase the organism's chances of
finding a mate.
Answer:
B
Explanation:
B is the correct answer because the environment effects how the body has to adapt.
A beneficial mutation is not always considered beneficial because: (B) It depends on the organism's environment.
While a beneficial mutation can provide advantages to an organism in certain environments or circumstances, its benefits may not be universal. The suitability of a mutation depends on the specific environmental conditions in which the organism finds itself. Organisms inhabit diverse environments with varying challenges and selective pressures.
A mutation is a change in the DNA sequence of an organism's genetic material. Mutations can occur naturally due to errors during DNA replication or as a result of external factors such as exposure to radiation, chemicals, or certain environmental conditions.

What is the scientific evidence for the creation of humans by a deity?
Answer:
Here is the scientific proof that God exists. Look at the universe. Look at humans, animals, plants, and every living thing. How did these things become alive? Did they just exist out of nowhere? God created them. You simply can't argue that everything just existed. Everything has a creator. 0+0+0 cannot ever become 1. God is the only thing that exists without a creator, because God is the only creator who made everything. Look at the insane complexity of life. For example, look at humans. We are the most complex thing alive. We are made perfectly with intelligence that onbody on this earth can ever even come close to. Our little minds can only do so much. God is the one and only who can create life. Can we ever make something become alive? Obviously no. If the whole world would come together we wouldn't be able to make a single living fly..

n a strain of tomato plants, short plant height and small fruit size are traits that display autosomal recessive patterns of inheritance. To investigate whether the traits segregate independently, researchers cross a pure-breeding line of tall tomato plants that have large fruits with a pure-breeding line of short tomato plants that have small fruits. The researchers observe that all the plants in the F1 generation are tall and have large fruits. The researchers cross the F1 plants with one another to generate an F2 generation. The researchers record observations for the F2 generation and will use the data to perform a chi-square goodness-of-fit test for a model of independent assortment. The setup for the chi-square goodness-of-fit test is shown in Table 1.The researchers choose a significance level of p=0.05. Which of the following best completes the chi-square goodness-of-fit test?
For researchers who choose a significance level of p=0.05, the chi-square value, the critical value is mathematically given as

How could you take a protein with a known sequence of amino acids and use it to create an artificial gene?
It is possible to take a protein with a known sequence of amino acids and use it to create an artificial gene due to the genetic code.
What is the genetic code?The expression genetic code makes reference to certain triplets of nucleotides or codons that encode specific amino acids.
In consequence, it is possible to design a specific nucleotide sequence in order to synthesize a protein.
The genetic code shows how genetic information flows from DNA to RNA and then to protein.

Peppered moths come in two color variations, as shown below.
Prior to the Industrial Revolution, the majority of the population in England consisted of the light colored variation. The dark colored moth became the dominant variation by the end of the 20th century and remained so for almost 100 years. Today, the light colored variation is dominant again.
What is the best explanation for this?
A. Populations with two variations have a better chance of survival than populations with more.
B. A single variation can be beneficial under some conditions and harmful under other conditions.
C. One variation will always be harmful, and the other will always be beneficial.
D. A single variation can be beneficial in all conditions or harmful in all conditions.
The answer, I do believe, should be option B. Here's my reasoning...
The question doesn't ask about a bunch of other species and how the moth variations relate to the survivability of many species, so I think that rules out option A. Option C is too black-and-white, because the explanation above simply states how a moth was able to survive better on different color variations. The last option, D, is also too black-and-white. So I believe that the answer is B, because sometimes, like prior to the Industrial Revolution, the one variation is better (as seen in the upswing of dominance in different variations).

Lewis is exercising and his muscles need oxygen. Which best describes how systems interact to bring his body into homeostasis? The circulatory system brings oxygen to the respiratory system, which delivers oxygen to the muscular system. The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system. The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the skeletal system. The circulatory system brings oxygen to the respiratory system, which delivers oxygen to the skeletal system.
The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system. Therefore, option (B) is correct.
What is respiratory system?The respiratory system is the biological system that facilitates the exchange of gases between an organism and its environment. It is responsible for the intake of oxygen, which is used for cellular respiration and energy production, and the removal of carbon dioxide, which is a waste product of cellular metabolism. The respiratory system includes the lungs, airways, and other structures involved in breathing.
The respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide, while the circulatory system transports oxygen-rich blood from the lungs to the muscles, where it is needed for energy production. The muscular system then uses the oxygen to produce energy and power movement. These systems work together to ensure that Lewis's body is able to maintain a state of balance, or homeostasis, during exercise.

Answer:
Mutations are random, but natural selection is not random. Different mutations can cause the same phenotype. Evolution repeats itself in different environments.

Introduced by Charles Darwin, natural selection is the idea that a species adapts to its environment through changes in its genetics. Natural selection is not random, though the genetic changes (or mutations) that are filtered by natural selection do come about randomly.
