Answer:

Hewo! Mizuki here to help! The correct answer would be option A!

Explanation:

Oki! So.... we find out the length, width, and height first!

The equation for finding the length: 36 ÷ 2

And the answer will be 18, make sure to memo it if your following along!

The equation for finding width: 36 ÷ 3

And the answer will be 12, so yeah(I tried it with 2 because it was 2 prism long, but it turned out to be a number not on the list [3888])

The equation for finding height: 24 ÷ 2

And the answer will be 12!

Is there an impact on the environment if blue whales went extinct?

Answers

Answer:

Yes.

Explanation:

Blue whales are the largest animals in the world, and they are the apex predator in the ocean, meaning they help to regulate the population of other species in the ecosystem. As with any species, the loss of blue whales would cause imbalances in the food chain, which would have far-reaching effects throughout the ocean and its inhabitants. In addition, blue whales help maintain the balance of carbon dioxide in the ocean which could be lost if the species were to go extinct.

Why does the water condense in the first tank when the oxygen and nitrogen do not?

Answers

the molecules in those gases have very little kinetic energy to push molecules apart. Because of this, the attraction between the molecules pulls them together and condenses the gases into a liquid, just like the water in the first tank. ... When the nitrogen evaporates, the liquid left behind is mostly oxygen.

Is it possible for you to find out whether a plant has taproot or fibrous roots by looking at
the impression of its leaf on a sheet of paper? Think and explain the answer.

Answers

Answer:

No, it is not possible to determine whether a plant has taproot or fibrous roots by looking at the impression of its leaf on a sheet of paper. This is because the root system of a plant is hidden underground and cannot be seen from the surface. The shape and size of a leaf can provide clues about the type of root system a plant has, but the impression of a leaf on a sheet of paper does not provide enough information to definitively identify the type of root system.

Explanation:

A CBC specimen was rejected for testing by the hematology department. The tube was filled completely and labeled properly. What might have been the reason for rejection?

Answers

Answer:

Explanation:

The only thing I can think of is that if you are testing blood for a CBC, you are sometimes required to reject the 1st sample. Perhaps the technician forgot to take a sample that is just meant to be pitched or it was improperly labeled. I get my blood checked every other week, and the people who take it out are scrupulously careful in making sure that the first tube is labelled as waste. No one has every made the mistake of not doing it, but I can see it happening.

The question says it was properly labeled. I didn't see that. The only other thing I can think of is that the machine improperly recorded what the blood cells were and the numbers were all out of kilter.

Carbon dioxide moves through the plasma membrane through the process of

A. osmosis
B. active transport
C. diffusion
D. facilitated diffusion
E. both diffusion and osmosis​

Answers

As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood. Therefore the answer is C

what is a non example of crystallization​

Answers

Answer:

Microscopically, a single crystal has atoms in a near-perfect periodic arrangement; a polycrystal is composed of many microscopic crystals (called "crystallites" or "grains"), and an amorphous solid (such as glass) has no periodic arrangement even microscopically.

Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. ... The third category of solids is amorphous solids, where the atoms have no periodic structure whatsoever. Examples of amorphous solids include glass, wax, and many plastics.

In condensed matter physics and materials science, an amorphous (from the Greek a, without, morphé, shape, form) or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal. In some older books, the term has been used synonymously with glass.

Explanation:

This chapter highlights mesocrystals as an interesting example of particle‐mediated, non‐classical crystallization processes. Mesocrystals — the shortened name for mesoscopically structured crystals — are superstructures composed of nanoparticles, being arranged three‐dimensionally in crystallographic register. Mesocrystals are often only intermediate structures in a non‐classical crystallization pathway leading to a final single crystal by nanoparticle fusion. Therefore, they are difficult to detect. Although mesocrystals were initially described for synthetic systems, recent investigations have revealed an increasing number of bio‐mineral systems which appear to be mesocrystals, but which so far have been considered to be single crystalline, including nacre and sea urchin spines. This chapter briefly defines non‐classical crystallization processes, provides some examples of synthetic mesocrystals and mesocrystals in biomineralization, and attempts to provide some insight into their formation mechanisms, despite their being as yet largely unexplored.

On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, and the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:

Muppet hair color as a function of two-locus genotypes

Two-locus genotype Muppet hair color
A_B_ Cookie monster blue
aaB_ Elmo red

Explanation:

Available data:

Two diallelic genes acting in a recessive epistatic manner to express hair colorAllele A is dominant over the allele aAllele B is dominant over the allele bA_B_ Cookie monster blue aaB_ Elmo red __bb Janice blonde

When talking about epistasis, we are referring to an interruption. These are interactions between genes located in different loci in the same chromosome. An epistatic gene can alter, influence, or suppress the expression of a hypostatic gene. When the epistatic gene is recessive, the interaction is known as recessive epistasis.  

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.  

In recessive epistasis, the proportion is 9:3:4.

MR. NIGER A.D.

M: Movement

R: Respiration

N: Nutrition

I:  Irritability

G: Growth

E: Excretion

R: Reproduction

A: Adaptation

D: Death

There are other qualities such as  

possession of Cells and DNA  (a living thing may be unicellular or multicellular)ability to Metabolize, that is, ingest and convert and absorb nutrients Homeostasis: This is the ability of an organism to regulate its internal environment Interaction with living and non-living things

All the above make it easy to distinguish between matter that has life and that which doesn't.

Answers

According to the given that actual flower position is dominant over terminal flower.

What is a homozygous dominant plant?

When an organism possesses two copies of the same dominant allele, it is said to be homozygous dominant, and when it possesses two copies of the same recessive gene, it is said to be homozygous recessive.

When an organism is homozygous, it contains two copies of the same allele for a gene. When two copies of the same dominant allele or two copies of the same recessive allele are present in an organism, it is said to be homozygous dominant or homozygous recessive.

When an organism is heterozygous, it has two distinct alleles of the same gene. For instance, pea plants can have either homozygous dominant (red-red) or heterozygous red blooms (red-white). They are homozygous recessive if they have white blooms (white-white). Heterozygous carriers are always present.
