Answer:
How human activity can cause disruptions in the ecosystem?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Explanation:
In an ocean ecosystem, an overgrowth of giant kelp has developed. Crabs love to eat this type of plant. How will this overgrowth of kelp impact the crab population?
Answer:
Due to there being more kelp, more crabs will survive and this will increase the crab population.

Oxpeckers have a mutualistic relationship with rhinoceros. Oxpeckers eat the ticks that are on the rhinoceros.
Which of the following describes how the energy flows in this relationship?
(1 point)
The energy flows from the tick to the rhinoceros, and then from the rhinoceros to the oxpecker..
The energy flows from the rhinoceros to the tick, and then from the tick to the oxpecker.
The energy flows from the rhinoceros to the oxpecker, and then from the oxpecker to the tick.
The energy flows from the oxpecker to the tick, and then from the tick to the rhinoceros.
Answer:
The energy flows from the rhinoceros to the tick, and then from the tick to the oxpecker.
Explanation:
The ticks suck the blood from the rhinos, and the oxpecker eat the ticks.
Mendel's principles of heredity apply to many organisms, including animals. For example, in guinea pigs, black fur (B) is dominant over white fur (b). What are the possible genotypes for fur in each of the two guinea pigs shown here?
In guinea pigs, the gene for black fur, B, is dominant over the gene for r white fur, b recessive, so the possible genotypes for fur in each of the two guinea pigs are BB X bb = Bb, Bb, Bb, Bb.
What are genotypes?
Genotype is the genetic appearance of the organism which shows all the traits in the genetic appearance but in the physical aspect, it only shows the dominant trait.
The cross between BB X bb
Gametes: B and b
Genotype = Bb, Bb, Bb, Bb.
Phenotype: all offspring are having black fur.
The cross is attached in the image below.
From the analogy shown, it is obvious that one parent has a gene with black fur and the other has white fur. During such crossing, the offspring are two homozygous dominant black fur and two homozygous recessive black fur.
Therefore, genotypes for fur in each of the two guinea pigs are BB X bb = Bb, Bb, Bb, Bb.

Which statements are true about nuclear fusion?
(select multiple)
a. For nuclear fusion to occur a nuclei must split to create energy.
b. For nuclear fusion to occur two nuclei must combine to produce energy.
c. Nuclear fusion produces more energy than nuclear fission.
d. No atoms are involved in nuclear fusion.
e. Energy is converted to mass during nuclear fusion.
f. The sun's energy is produced from nuclear fusion.
Answer:
b, e, and c
Explanation:
The correct option for nuclear fusion are for nuclear fusion to occur two nuclei must combine to produce energy and Nuclear fusion produces more energy than nuclear fission.
What is nuclear fusion?
The Sun and other stars are powered by nuclear fusion reactions. A heavier nucleus is created when two light nuclei fuse together in a fusion reaction.
Because the mass of the resulting single nucleus is smaller than the combined mass of the two initial nuclei, the process produces energy. Remaining mass is converted to energy.
Fusion energy could be a significant source of energy generation if scientists can figure out how to use it in equipment on Earth.
The periodic table contains a wide variety of elements that can undergo fusion. The deuterium-tritium (DT) fusion reaction, however, is of particular interest to scientists working on fusion energy applications.
Therefore, The correct option for nuclear fusion are for nuclear fusion to occur two nuclei must combine to produce energy and Nuclear fusion produces more energy than nuclear fission.

Abiotic and biotic factors in an ecosystem are interrelated. In nature, when one factor is changed or removed, the availability of other resources will be impacted. Which of the following is an example of an abiotic factor impacting a biotic factor?
1.What process can cause rock to move deep underground?
2. What process can cause rock to move up to Earth's surface?
Answer:
1.) "Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment (and soil) from the place of weathering. Liquid water is the main agent of erosion. Gravity and mass wasting processes move rocks and sediment to new locations."
2.) "Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away."

Which statement best explains why cell differentiation is essential to the structure and function of multicellular organisms?
It makes the cells grow larger as the body grows.
It fixes mutations in DNA that were created during replication.
It produces the proteins needed for chemical reactions to keep the body moving.
It creates the specialized cells needed to form tissues and organs.
Cell differentiation is essential to the structure and function of multicellular organisms because it creates the specialized cells needed to form tissues and organs. Hence, option D is correct.
What do you mean by Cell differentiation?Cell differentiation may be defined as the generation of specialized cell types which is structurally and functionally distinct.
It also involves the process during which a cell ceases to divide and develops specialized structural elements and distinct functional properties.
Therefore, the correct option for this question is D.

if the density of water is 1 g/ml, what is the mass of 3ml of water?
PLEASE HELP
You can use dimensional analysis to figure this out.
[tex]=3\ ml[/tex] × [tex]\frac{1g}{ml}[/tex]
= 3 grams
If done correctly, ml and ml will cancel out, leaving you with grams.
If you don't know dimensional analysis, simply multiply 3 ml by 1 grams and that should still get you 3 grams.
Answer:
3 grams

what are three ways in which plant cells differ from animal cells
Answer:
1.Plant cells have a cell wall, but animals cells do not.
2.Plant cells have chloroplasts, but animal cells do not.
3.Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
Explanation:
Hope this helps, sorry if I'm wrong
Brainliest would be nice. :)
Answer:
In the plant cells, it is noticeable that there's a cell wall, which basically consists of cellulose, and is responsible for guaranteeing resistance and form to the cell, also protecting it from pathogens, a Characteristic that isn't found on animals cells.
The format of the cells is also different due to the animal cells being round and having an irregular form, while plant cells have fixed and rectangular forms.
The plastids are organelles that are exclusive to the plant cells and are characterized by the presence of double-membrane and DNA. They possess the function of storing and photosynthesis.
Note: The difference between these cells is a lot, and is mainly based on the presence and absence of organelles.
