Answer:

The statement which states that cell has a dual existence of being the smallest fundamental unit of life and can also be a part of a multi cellular organism is TRUE.

Explanation:

According to cell theory, cells is the basic unit of life that can be found in all living organisms. There are two basic types of cells, these are prokaryotic and eukartyotic cells. Prokaryotic cells are very primitive in nature and are usually found in very small living organism. These organisms usually exist as unicellular organisms. This means, that a unicellular organism is made up of only one cell, which carry out all the activities that the organism needs to survive.

Multi cellular organisms on the other hands are made up of many cells, which work together to perform diverse functions. Thus, cells have the capacity to exist alone as a single cell and as part of group of cells.

Predict what the calf produced in a union between each of these parents might look like. Explain your answers.
Charra [1.4K]
We know that purebred means that the organism contains the same alleles for the trait and hybrid means that it contains two different alleles for the trait. Dominant means that it will be shown in a hybrid and a purebred, but recessive traits will only be shown in purebred recessive organisms.

a) The offspring of a purebred white (recessive) cow and a purebred brown (dominant) bull, would be all hybrid brown (dominant). This is because as I stated above, dominant traits are shown when the offspring has both dominant and recessive alleles for the same trait.

b) The offspring of a purebred brown (dominant) cow and a purebred brown (dominant) bull would all be purebred brown (dominant). This is because if both of the parents have only alleles that code for brown color, the only color that the offspring can be is brown.

c) The offspring of a purebred white (recessive) cow and a purebred white (recessive ) bull would all be purebred white (recessive), for the same reason stated above in part b), the only difference being that the alleles are recessive and code for white color instead of being dominant and coding for brown color.

d) The offspring of a hybrid brown (dominant) cow and a purebred white (recessive) bull would be half hybrid brown (dominant) and half purebred white (recessive). This can be seen best if you set up a Punnett Square, which is a diagram that shows allele frequencies in offspring. This shows you that the chance that the offspring get the dominant allele from the mother cow is 50%, thus 50% would be hybrid brown (dominant), as the father can contribute only a recessive white allele. The other 50% would be purebred white (recessive) because the mother cow would be contributing a white allele and so would the father.

Hope this helps! :)

The result of the following cross indicates the orange eyes are _____ black eyes. Two aliens of the P generation are crossed. Bo
Dima020 [189]

Answer:

<h2>Recessive to </h2>

Explanation:

1. As given here, both parents are black, and their 247 progeny out of 333 are black, it  clearly indicates that 3/4 progeny is parental phenotype and 1/4 is different type.

2. This clearly show that both parents are heretogyzous, one allele is dominant and one is recessive.

3. Here black is dominant over blue.

4. Dominant allele express them-self in dominant homogyzous as well as heterogyzous condition.

The table describes two methods of heat transfer. Methods of Heat Transfer Method A Method B Transfer of heat is through vibrati
Virty [35]

Answer:

Method A is conduction and Method B is radiation.

Explanation:

Driving the situation in which the heat spreads through a "conductor". That is, although it is not in direct contact with the heat source, a body can modify its thermal energy if there is heat conduction by another body, or by another part of the same body. For example, while cooking something, if we leave a spoon against the pan, which is on the fire, after a while it will heat up too.

Heat is energy in transit. This energy is transported by means of electromagnetic waves in the infrared frequency. In the transmission of heat by radiation, this fact is more evident. All bodies emit radiation, just having a temperature. The only difference between light and heat is the frequency of radiation. Thermoses are a good example of thermal radiation. The walls of the thermos are double and silver. The double walls are separated by practically a vacuum, in such a way that the heat exchanges by conduction or convection are minimized, as they need a material medium to occur. The silver walls, on the other hand, minimize heat exchanges by radiation, thus making sure that the liquid inside the bottle does not lose or receive heat.
