Answer:

B. Nonvascular plants are typically smaller than vascular plants.

Explanation:

The Non- vascular plants are made up of bryophytes, they are found in nitches and they have no vascular tissues, no leaves, no seeds. They so not have true roots but rhizoids that holds them to the ground. They usually small. Example include liver wort, mosses.

While vascular plant are plants that are Characterized with the presence of conducting tissues such as zylem and phloem and are referred to as land plant.

Vascular are usually bigger in size than the non-vascular plants unlike non-vascular plants they have leaves, root and step.

Which term describes the fusion of two gametes to form a diploid zygote?

SpyIntel [72]

Answer:

The fusion of two gametes to form a diploid zygote is called SYNGAMY.

Explanation:

During sexual reproduction process, exchange of DNA usually occur and this introduces diversity into the offspring that are produced. One of the ways by which exchange of DNA take place is called syngamy. Syngamy involves the bonding together of two sex cells leading to the formation of cell that has double amount of the chromosomes in the parent cells. The two cells that bond together are called gametes while the diploid cells formed is called zygote. The major function of syngamy is creation of variation; the genotypes in the formed zygote differ from those of the gametes.

Plant cells can better tolerate exposure to hypotonic solutions than can animal cells. Which one of the following helps to best

anzhelika [568]

Answer:

b. The rigid cell walls limit how far plant cells can expand and exert a back pressure to limit further water uptake.

Explanation:

Plant cells have a rigid cell wall made of cellulose. Animal cells lack a cell wall.

When the plant cells are placed in a hypotonic solution, water enters into the cells and the cells expand. However, after a certain limit, the cell wall exerts wall pressure on the contents of the cell and does not allow it to take more water in. The wall pressure from the cell wall of plant cells protects them against bursting when placed in a hypotonic solution.

Animal cells burst out due to intake of water by osmosis when placed in a hypotonic solution. They do not have a cell wall to protect them from bursting.

Last year, one county reported that among 3000 Caucasian women (group 1) who had babies, 95 had multiples (twins, triplets, etc.

vladimir2022 [97]

Answer:

Explanation:

According to the statistics, the chances that a Caucasian women will have multiples are 3.17%, while an African American women has chances of 3.33%. The chances of the women from this two different racial groups having multiples are very similar, almost identical, so it can not be said that the race is a detrimental factor in having multiples or not. The multiples have been noticed to be in much higher percentages, but that has been the case in only certain regions, so it is not based on race, but more of a regional gene pool that has those traits. Such example is Nigeria, where there is high percentage of multiples, but the people of the same race surrounding Nigeria have much lower percentages of multiples.
