The series of diagrams below represents a process carried out by a unicellular organism. This process is know as
Phagocytosis is a crucial mechanism by which cells engulf and absorb foreign substances. This method is how small, unicellular organisms like free-living amoebas obtain food. Thus, option B is correct.
What phagocytosis process carries by unicellular organism?Phagocytes, a type of living cell, devour or engulf other cells or particles through a process known as phagocytosis. An amoeba or other free-living single cell could make up the phagocyte, or it could be one of the body's cells, like a white blood cell.
In unicellular creatures, phagocytosis is a critical mechanism for nourishment; in multicellular organisms, it is a function of specialized cells called phagocytes.
Therefore, Phagocytosis is a process used by some single-celled protists, such as amoebae, to absorb food particles.

Answer: D is right
Explanation: It seems both waves have same wavelength.
Because speed = wavelength · frequency (v = λf) and
f = v/λ, so frequency is same. Because period T = 1/ frequency, also periods are same. Wave Y has higher amplidude and its energy is greater.

Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.
