Which of the following tissues, cells, or structures in flowering plants is a part of the sporophyte generation and therefore di
jeka94

Answer:

Cell of and integument

Explanation:

When flowering plants reproduce by sexual reproduction, they form seeds contained into fruits. The fruit is derived from the maturation of the flower's ovary (female part) after fertilization.

A mature seed contains three generations:

  1. a diploid embryo (the new sporophyte),
  2. The embryo is surrounded by haploid female gametophyte tissue that supplies nutrition
  3. All the above structure is in turn surrounded by the seed coat (diploid parental sporophyte tissue). The seed coat is produced by integument cells to protect the embryo during its development and before its can germinate. As it is produce by it parental plant, its ploidy level diploid.

In contrast, the generative nucleus and sperm cell are part of male gametophyte (pollen grain) and therefore haploids. Synergid cell is part of embryo sac, therefore belongs to female gametophyte and thus being haploid. Finally, cell of endosperm is usually derived from the fusion between a sperm cell and one of the two female gametes present within the embryo sac, thus being triploid.

Why is it sometimes hard to establish an MPA?
Dmitriy789 [7]
<h2><em>Why is it sometimes hard to establish an MPA?</em></h2>

  • <em>Arguably, it is difficult to declare such an MPA successful, when <u>the human populations responsible for degradation have been removed</u>, and its mere establishment is rife with such political contention. Issues also arise when considering the resources needed to support a large-scale MPA.</em>

How do changes in nutrient levels affect the structure of aquatic food webs?
vodka [1.7K]

ANSWER:

The effects of increasing or decreasing the nutrient levels in an aquatic food webs is described in the explanation.

Explanation:

If the nutrient levels in an aquatic food web increase moderately then it will result in increased production of the primary producers and the consumers.

But if the nutrient levels are increased excessively, like in eutrophication, then the increased level of nutrients will result in overproduction of the consumers like fishes, etc. Hence, there will be a scarcity of resources like oxygen in the water to support them and this will lead to a decline in biodiversity of the aquatic food web.

If the nutrient levels are decreased, then there will be competition for resources among the species which will ultimately lead to the decline of some species from the aquatic food web.

No stripe on the head (H) is dominant, a black stripe on the head is recessive. If dad's genotype is Hh, what are the odds that
olga55 [171]

The chance of the offsprings with stripe on head is 50%.

Option A.

<h3><u>Explanation:</u></h3>

Here according to the figures, the male is the brown one which has no stripe on his head as mentioned, and the female is the pink one who has a stripe on her head. The gene for the head stripe is denoted by H.

So the genotype of the father which is given as Hh. He is heterozygous.

The genotype of the mother should be hh as she has stripe and she must be homozygous recessive to have it.

So the gametes from father is H and h. Whereas the gametes from mother is only h.

So the genotype of the offsprings are Hh and hh as 50% each.

So the probability of the offspring being striped head is 50%.
