Water escapes from the pores in plant leaves because of evaporation. This water is what keeps the vacuoles in the cells full and shaped, so the vacuoles are like deflating water balloons

The reason why wilting of leaves take place in hot summer days is mainly because of its water management
in hot summer days, stomata of plants (which located on their leaves, are closed in order to conserve water)

The solution should become hypertonic.

A solution will be called hypertonic if their oncotic/osmotic pressure is higher than the body fluid. When a hypertonic solution is administered, they will attract water from the nearby membrane. This will make a nearby cell become shrink as they lose water. This might be dangerous as the cells as they might go lysis if the amount of water loss is too many.
After the salt absorbed, it will be dumped by kidney into urine. But the salt will also attract water, so you will lose some fluid and might become dehydrated. This is why drinking sea water is dangerous because it will cause more fluid loss in urine.

Calix’s karyotype showed that he has a genotype of XXY. Explain how nondisjunction caused Calix to be XXY.
Juli2301 [7.4K]

Answer:

A XY or XY gamete fuses with a normal gamete (X or Y)

Explanation:

Meiotic nondisjunction is the phenomenon whereby chromosomes fail to separate during meiosis I or II. Meiotic nondisjunction leads to the formation of abnormal gametes I.e. gametes with additional or missing chromosomal piece.

The fusion of these abnormal gametes produced by nondisijuction with a normal gamete (X or Y chromosome). This leads to a condition called ANEUPLOIDY, which is a chromosomal disorder. In the case od Calix, XXY is an ANEUPLOIDY state that could have resulted because there was a fusion between a XX gamete and Y gamete or XY and X. The XY or XX gametes are produced as a result of nondisijuction.

Until the , only one-celled organisms lived on land, but during this period, plants became abundant.
Anestetic [448]

The answer is Silurian period (443 million to 416 million years ago). This was the era when life in the seas and oceans began to conquer land. This is associated with a period of warm climate, rising sea and ocean levels hence giving shallow-water grounds where reefs developed. Plants like bryophyte began to develop including the emergence of terrestrial arthropods

Anarel [89]

Answer:

This question lacks options, the options are:

A) symbiosis

B) ecosystem

C) community

D) population

E) biosphere

The answer is D) Population

Explanation:

Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.

This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.

This observation completes what a POPULATION is all about, hence, a population was observed.
