Answer:
Epithelial cells are the protective cells. They form the outer covering of the body surface which protects the body from any external danger.Cuboidal epithelial cells, as their name suggests, are shaped like cubes. These are typically found in tissues that secrete or absorb substances, such as in the kidneys and glands. Columnar epithelial cells are long and thin, like columns. These are usually found in places that secrete mucus such as the stomach.

how does nuclear fusion energy reach earth
Answer:
Scientists are searching for ways to create controlled nuclear fusion reactions on Earth. Their goal is develop nuclear fusion power plants, where the energy from fusion of hydrogen nuclei can be converted to electricity. In the thermonuclear reactor, radiation from fusion is used to heat water and produce steam.

When observing a specimen under medium power, which adjustment knob should be used to focus the image? Why?
Answer:
The coarse adjustment knob should only be used with the lowest power objective lens. Once it is in focus, you will only need to use the fine focus. Using the coarse focus with higher lenses may result in crashing the lens into the slide.
Explanation:
A scientist crossed two fruit flies in a lab. She was studying the transmission of the alleles that affect wing shape. The dominant allele, C, is the allele for curly wings, and the recessive allele, c, is the allele for straight wings. She knew that one of the parent flies was heterozygous and had curly wings (Cc). Half of the offspring from the cross had curly wings, and the other half had straight wings. Identify the genotype and phenotype of the second parent fly. State the evidence that supports your response.
Answer:
The other fly would have to be a cc
Explanation:
To do this, you can use the square method, one Cc's on the top and one side a cc, when you cross these it gives you Cc, Cc, and cc, cc. Half and half.
Hope this helped!
The other parent was cc.
Genes often occur in pairs. Genes are units of inheritance located in the chromosomes. The pairs in which genes occur are called alleles. In a given pair of alleles, one gene is dominant and the other is recessive.
In this case, the dominant gene is for curly wings and the recessive gene is for straight wings. If one parent is Cc , the other parent must be cc causing half of the offspring from the cross to have curly wings, and the other half to have straight wings.

If one substance floats in another it must be dense
True
Or
False
Answer:
true
Explanation:
Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.

Diffusion is the movement of molecules from an area of high concentration of molecules to an area with a ____ concentration.
A. Equal
B. Higher
C. Lower
D. None of the above
Answer:
lower
Explanation:
Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. So, the correct option is C.
What is diffusion?Diffusion is a type of passive transport, this means that it does not require any kind of external energy for movement of molecules. The difference in concentration in two areas gives rise to a concentration gradient. Where, in one area there is high concentration of molecules and in another, there is low concentration of molecules.
If the molecules move from an area of higher concentration to an area of lower concentration, they are moving along the direction of concentration gradient. This is why no additional energy is required. Diffusion is a type of passive transport where molecules move along a concentration gradient.
This is in contrast to active transport where molecules move against the concentration gradient and therefore require external energy.
Therefore the correct option is C.

Write the overall equation for photosynthesis using words?
Answer:
carbon dioxide + water =glucose +oxygen
Explanation:
hope this helps :)
The overall equation for photosynthesis using words is:
Carbon dioxide + water + sunlight energy → glucose + oxygen
Photosynthesis in plant chloroplasts and photosynthetic microorganisms is a complex metabolic process. Photosynthesis equation: [tex]CO_2 + H_2O + sunlight = glucose (C_6H_{12}O_6) + O_2.[/tex]
Photosynthesis converts carbon dioxide and water into glucose and oxygen. Special pigments like chlorophyll collect sunlight and transform it into chemical energy.
Photosynthesis underpins the food chain and sustains life on Earth. Primary producers, plants synthesise glucose that sustains all other organisms' growth and development. Photosynthesis provides oxygen for respiration and regulates carbon dioxide levels, preserving Earth's atmosphere.

Give an example of an adaptive radiation. Provide evidence to support the claim that the radiation originated with one or a few species, that it was rapid and the descendant groups occupy a wide array of ecological niches. Suggest a hypothesis to explain why the radiation occurred.
Answer:
An example of an adaptive radiation with evidence to support the claim that the radiation originated with one or a few species is discussed below in details.
Explanation:
The method of evolution of various classes in a given geographical area originating from a spot and spreading to other regions or habitat is described as adaptive radiation. For example, modifications in nozzles of finches on Galapagos island.
Adaptive radiation indicates the adaptation of an organism that allows it to favorably spread, or radiate, into other circumstances. Adaptive radiation commences to speciation and is only used to explain living organisms.

a)what are the difference between two species of minnows?
Animals are often individually consistent in their behavior, not only over time, but also across different functional contexts. Recent research has focused on phenotypic and evolutionary mechanisms explaining such personality differences through selection. Parasitism and predation induce important mortality and fitness costs, and are thus main candidates to create and maintain personality differences in the wild. Here, we present data on the behavioral consistency of the Eurasian minnow (Phoxinus phoxinus) from two populations that live in different tributaries of the same river, but whose ecological environment differs fundamentally with regard to predation and parasitism. We experimentally demonstrate that individual minnow in both study populations are consistent in their boldness and activity. However, the two study populations differ notably: in the high predation and parasitism risk population fish show higher mean boldness, but tend to be less active than fish in low predation and parasitism risk population. Parasite (Diplostomum phoxini) load was negatively, but not statistically significantly, associated with fish activity level. Our study suggests that parasitism and predation are likely important agents in the ecology and evolution of animal personalities.
