Which part of the cell does this illustration represent?
Calvin cycle center
mitochondria
cytoskeleton
endoplasmic membrane system
Answer:
Mitochondria
Explanation:
The mitochondrion is an organelle found in both animal and plants cells. However, it is not found in prokaryotic cells. The mitochondrion is most famously known as the powerhouse of the cell because it produces ATP. The defining visual feature of mitochondria is the wavey-like pattern within the organelle.

how do you propagate trees
Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.

Why is the muscular system needed for respiration to occur in the human body?
Answer:
Explanation:
the muscular system is needed for respiration to occur in the human body because the diaphragm is a muscle iteslf and the diaphragm inflates the lungs
Cellular respiration is a complex process that
1- occurs before autotrophs are able to carry out photosynthesis
2- occurs only in animals that take in oxygen
3- is performed only by organisms that are incapable of photosynthesis
4- breaks down organic molecules to release stored energy

Which type of resources form much more slowly than we use them? A: reusable B: renewable C: nonreusable D: nonrenewable
The type of resources from much more slowly than we use them is non-renewable resource. The correct option is D.
What are nonrenewable resources?A non-renewable resource is a natural resource that cannot be replaced quickly enough by natural means to keep up with consumption.
Carbon-based fossil fuels are one example. With the help of heat and pressure, the original organic matter is converted into a fuel such as oil or gas.
Nonrenewable energy sources are not only affecting our planet's atmosphere by increasing greenhouse gas emissions.
Coal and oil combustion emits particles that can pollute the air, water, and land. Some of these particles are captured and stored, but many are released into the atmosphere.
The use of fossil fuels also disrupts Earth's "carbon budget," which balances carbon in the ocean, earth, and atmosphere.
Thus, the correct option is D.

Which of the following is NOT part of the non-specific immune response?
A. Inflammation
B. Phagocytosis
C. Antibodies
D. Interferons
D. Interferons are not a part of the non-specific immune response.
What is the function of interferons?Interferons were first described as an antiviral thing that interferes with viral replication in mammalian cells (10). they're secreted from inflamed cells and spark off an innate immune reaction that promotes now not best cytokine production but additionally herbal killer mobile features and antigen presentation.
Interferons (IFNs) — the body's first line of antiviral defense — are cytokines that are secreted by host cells in reaction to virus infection. by using inducing the expression of hundreds of IFN-inspired genes, numerous of that have antiviral capabilities, IFNs block virus replication at many ranges.
Interferons are a circle of relatives of clearly-happening proteins which are made and secreted with the aid of cells of the immune gadget (an example, white blood cells, natural killer cells, fibroblasts, and epithelial cells).

Which of the following sentences state a significant conclusion that Gregor Mendel drew from his experiments with pea plants? Traits are inherited in discrete units and are not the result of "blending." Genes are composed of DNA. Recessive genes occur more frequently in the F1 generation than do dominant ones. There is considerable genetic variation in garden peas.
Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."
------------------------
After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.
Mendel named dominant the expressed variant.
Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.
He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.
Mendel named recessive the second alternative variant.
Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.
These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors separated again during sex cells formation, producing two types of gametes, each with only one factor.Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.
He thought that alleles separate -segregate- during the process of gamete formation.
The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

Answer:
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
