Answer:

Please find the similarities and differences between these cells below.

Explanation:

According to this question, six specific cells are examined. They are: neuron, red blood cell, osteocyte, skeletal muscle cell, sperm cell, and egg cell.

SIMILARITIES:

These cells are cells that make up different tissues and systems in living organisms. They perform different functions in their respective locations, however, they are similar in the sense that they all possess some cellular components called organelles. The organelles that are common to all these types of cells are CELL MEMBRANE, RIBOSOMES, MITOCHONDRIA, GENETIC MATERIAL (DNA), NUCLEUS,

They also possess two set of chromosomes in their nucleus i.e. diploid.

DIFFERENCES:

However, they differ in their functions. For example;

- neuron: nerve cell whose function is related to the nervous system

- red blood cell: blood cell whose function is related to circulatory system

- osteocyte: bone cell whose function is related to the skeletal system

- skeletal muscle cell- muscle cell whose function is related to the muscular system

- sperm cell: a male sex cell whose function is related to reproduction

- egg cell: a female sex cell whose function is related to reproduction

Describe how population studies can be conducted in a school garden
daser333 [38]

Answer:

Population studies look at factors for one individual species.

Explanation:

In a garden, there are multiple species of plants growing. You could study different factors of each population, which is just all the individuals of one species in an area. For example, you could study how adding fertilizer affects the growth of tomato plants. To do this, you would have some tomato plants in the garden that have fertilizer added to the soil and some that don't. At the end of a certain period of time, maybe a month, measure the plants, find the average height and compare their growth. This is just one example, but there are lots of different things you could study.

In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t). Suppose a cross between a tall p
vazorg [7]

Answer:

Tt - 1/2

tt - 1/2

Explanation:

<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>

Tt   x   tt

Offspring = Tt   Tt   tt   tt (50% tall and 50% short)

If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):

Tt   x   tt

Offspring = Tt   Tt   tt   tt

Genotype ratio = 2Tt:2tt

Hence,

Tt = 1/2

tt = 1/2

Imagine that you want to breed a species of rose that has a wonderful smell. You have many different types of roses, but none of
Natalija [7]

Answer: if i want to breed a rose and i don't have a certain kind of rose, i have to cross between them until i have a kind of rose that express the phenotype i was looking for. Once i've got it, i'll try to cross it with another rose and generate more species like that to cross with the rose that express the phenotype, this favors to generate a specie that have a pure phenotype.

Explanation: The answer is explain by the Mendel's laws.

Mendel's second law:

if you have two roses that are heterozygous and you cross them, their offspring have a 25% probability of generating a homozygous phenotype for a certain recessive characteristic (such as the rich smell of roses that is not a dominant character), 50% of generate heterozygotes with a dominant phenotype, and 25% generate other homozygotes with a dominant phenotype.

Once the offspring with the recessive homozygous character are obtained, it is possible to start making crosses between those of a recessive nature and there Mendel's first law applies

All the homozygous recessive individuals that are crossed will have a 100% homozygous recessive offspring.

Also, if you cross heterozygotes with another heterozygotes the offspring will be 100% heterozygotes
