The food that animals and people eat comes from a variety of sources, including plants, animals, and other organisms, as plants are the primary source of food for most animals, including humans.
What is food for animals?They use photosynthesis to produce carbohydrates, proteins, and fats, which form the basis of their tissues. These nutrients are stored in different parts of the plant, such as the leaves, fruits, seeds, and roots, and can be harvested for human consumption. Animals also provide food for humans and other animals. Meat, dairy products, and eggs are some examples of animal-derived foods. Animals obtain their nutrients by consuming plants or other animals, and the nutrients get transferred up the food chain to other animals that feed on them.
Hence, The food that animals and people eat comes from a variety of sources, including plants, animals, and other organisms.

Answer:
answer is mid ocean ridges
Answer:
Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain
The term semiconservative replication refers to the fact that each new DNA molecule resulting from the replication process is "half-old, half-new." In the diagram, complete the replication required in the

Explanation:
As stated in this question, Semi-conservative model of DNA replication is the acceptable model of replication in which the two synthesized molecules of DNA consists of one new and one old strand each. DNA replication is carried out by an enzyme called DNA polymerase.
In the semi-conservative model, a double stranded DNA separates into two single strands. Each single strand is used as a template for DNA polymerase to synthesize nucleotides based on complementary base pairing i.e. For every Adenine base, Thymine is added and for every Guanine, Cytosine is added and vice versa.
In this question showing an image of a DNA molecule undergoing replication using semiconservative model, the first DNA molecule consists of the following nucleotides on the old strand and its synthesized nucleotides on the new strand:
Old strand - New strand
1. T - A
2. G - C
3. A - T
4. C - G
5. C - G
6. C - G
On the second DNA molecule, we have the following nucleotides on the old strand and its synthesized nucleotides on the new strand.
Old strand - New strand
7. A - T
8. C - G
9. T - A
10. G - C

The generation of a knock-out organism generally requires all the following EXCEPT ________. The generation of a knock-out organism generally requires all the following EXCEPT ________. knowledge of the sequence product embryonic stem cells knowledge of the target sequence a targeting vector
Answer:
knowledge of the sequence product
Explanation:
A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.

Characteristics of evolution in points.
Answer:
Five different forces have influenced human evolution: natural selection, random
genetic drift, mutation, population mating structure, and culture. All evolutionary biologists
agree on the first three of these forces, although there have been disputes at times about the
relative importance of each force. The fourth and fifth forces are new in the sense that they
are not explicated in more traditional texts. This is not an attempt to develop a “new”
theory of human evolution. Instead, the forces of population mating structure and culture
are arbitrary categorizations used to organize several different phenomena of human
evolution. Scientists agree on the phenomena themselves, although they do not always
organize them the same way.

Consider the food chain grasshopper mouse snakes hawks. If snakes go extinct what will happen to the food chain
Answer:
This can actually cause a major problem if the number of grasshoppers were to increase out of control. They eat plants and the number of plants,which are the basis of the food chain, could severely decrease which would impact all of the levels operating above this trophic level.
Answer:
Lack of mice
Explanation:
If the grasshopper where to go extinct the mice population would decrease. Which would lead to it being harder for snakes to find food or they would begin to rely on a different food source. But the hawks would be able to find less snakes but would overall be fine.

Explanation:
In rigor mortis, muscle tissue becomes locked in position because myosin heads are tightly attached to neighboring actin thin filaments. This lock-up is prevented in living muscle because ordinarily myosin is rapidly displaced from the thin filament by:_________.A. binding of a new molecule of ATP B. hydrolysis of ATP C. release of ADP after ATP hydrolysis D. release of phosphate after ATP hyrdolysis
Answer:
The correct answer is option A. binding of a new molecule of ATP.
Explanation:
Actin and myosin are complementary filaments present in muscle, actin is thin and myosin is a thick filament, these two filaments are responsible for the movement by muscle contraction and relaxation. Actin and myosin head shows great affinity towards one another.
Myosin heads are tightly attached to neighboring actin thin filaments due to its affinity to actin, however, myosin at other pockets also show a huge affinity for ATP. If myosin is bound to actin the affinity for ATP is changed and if new ATP bounds to the empty pockets it changes the conformation of myosin and prevents lockup or binding of the actin-myosin protein.

Explanation:
Step 1: Add approximately 25 mL of water to a 50-mL graduated cylinder.
Step 2: Measure and record the initial volume of the water to the nearest 0.1 mL.
Step 3: Carefully slide the object into the graduated cylinder. Measure and record the final volume of the water to the nearest 0.1 mL.
Step 4: Determine the volume of the object by subtracting the measurements in steps 2 and 3.
What pattern in these data could be used to predict the final volume if the initial volume is known?
The final volume is the sum of the initial volume and the volume of the object.
The initial volume is the sum of the final volume and the volume of the object.
The volume of the object is the sum of the initial volume and the final volume.
The final volume is the difference between the initial volume and the object’s volume.
Answer:
The final volume is the sum of the initial volume and the volume of the object.
Explanation:
Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.
From;
∆V= V2 - V1
V2= ∆V + V1

We find DNA on the ___, In every living cell that an organism owns
a. chromosomes
b. reproduction
c. mitosis
Answer:
A. Chromosomes
Explanation:
A Chromosome is some thing carrying genetic information in the form of genes.
We find DNA on the chromosomes, in every living cell that an organism owns. So, the correct option is A.
What is Chromosome?The word chromosome comes from the Greek words for color (chroma) and body (soma). Chromosomes are so named because they are cell structures, or bodies, that are strongly stained by certain color dyes used in research.
Chromosomes are defined as structures found inside the nucleus of a cell that are organized into genes from proteins and DNA. Each cell normally has 23 pairs of chromosomes.
These are threadlike structures which are made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell.
Therefore, the correct option is A.

Why does the cell sometimes have to expend energy to move individual molecules across the cell membrane?
Answer:
Normally, molecules move naturally down a concentration gradient [From an area of high concentration to an area of low concentration] by a process called diffusion. However, sometimes the concentration of the needed substance is higher in the cell than out of it, so the cell uses a different process called Active Transport. Unlike Diffusion, Active transport requires energy, as it is going against a concentration gradient.
Cells expend energy to move cells across the cell membrane as they use Active transport rather than diffusion.

which is true about both endocytosis and exocytosis? check all that apply
they use vesicles for cell transport
they require energy for cell transport
they remove wastes from the cell
they move small, fat-soluble substances
Answer: they use vesicles for cell transport and they require energy for cell transport
Explanation:
Both endocytosis and exocytosis use vesicles for cell transport, require energy for cell transport. The correct options are a and b.
What is endocytosis and exocytosis?Endocytosis is the transport of material into the cell, while exocytosis is the transport of material out of the cell.
The distinction can be seen because a vesicle forms around the molecule entering endocytosis. Exocytosis is basically the inverse of endocytosis.
Endocytosis and exocytosis both require energy in the form of adenosine triphosphate (ATP), which is used in the movement of substances into and out of the cell.
Endocytosis is classified into three types: phagocytosis, pinocytosis, and receptor-mediated endocytosis.
Exocytosis is the process by which vesicles fuse with the plasma membrane and release their contents outside of the cell. Exocytosis and endocytosis are both active transport processes.
Thus, the correct options are a and b.
