In what ways is the sporophyte generation of a moss dependent on the gametophyte generation?

Answers

The sporophyte generation of a moss dependent on the gametophyte generation is that it is used for support and most of its nutrients.A sporophyte  is the diploid multicellular stage in the life cycle of a plant or alga and it develops from the zygote produced.

Answer:

The sporophyte age of a greenery subject to the gametophyte age is that it is utilized for help and the vast majority of its supplements. A sporophyte is the diploid multicellular stage in the existence cycle of a plant or alga and it develops from the zygote created.  

Explanation:

A sporophyte is a multicellular diploid age found in plants and green growth that experience rotation of ages. It produces haploid spores that form into a gametophyte. The gametophyte at that point makes gametes that meld and develop into a sporophyte. In numerous plants, the sporophyte age is the predominant generation.A sporophyte is a plant that produces spores and a gametophyte is a plant that produces gametes. The word gametes allude to sperm and eggs.

A life science student uses a compound microscope to look at a slide of human tissue. He is not sure what part of the body the tissue is from, but makes an educated guess based on the cells he sees on the slide. There are hundreds of round disks with no nucleus, as well as a couple of purple-colored spherical cells. The student would most likely guess that the tissue is of: (A) Bone(B) Tymus(C) Blood(D) Muscle(E) Lung

Answers

Answer:

C

Explanation:

Blood contains red blood cells (erythrocytes) that do not contain nuclei and are biconcave to allow them to carry more oxygen for diffusion. Therefore the round disks with no nuclei are red blood cells.

The purple-colored spherical cells are probably blood platelets if they are small or they could be white blood cells (lymphocytes) if they are larger.

In humans, females inherit an X chromosome from each parent; males inherit their X chromosome from their mother and their Y chromosome from their father. The same is true of all other placental mammals: males produce X and Y gametes, and females produce only X gametes. In this system, referred to as the XX-XY system, maleness is determined by sperm cells that carry the Y chromosome. Yet the XX-XY sex determination system does not occur in all animal species. It is only one of a variety of systems within the animal kingdom. Above are Punnett squares illustrating three examples of gender inheritance patterns: humans, insects and birds. Consider both the illustration and the text. Compare the inheritance system of bird with that of humans.

Answers

In bird, females are heterogametic, produce two type of gametes. The two different sex chromosomes of a female bird has been designated to be the Z and W chromosomes. Whereas males have a pair of Z- sex chromosomes. Males are homogametic produce only one type of gametes with Z-sex chromosomes. Thus sex determination is ZW-ZZ type. In humans sex determination is XX-XY type. Males are heterogametic produce X and Y gametes and females are homogametic produce one type of gametes. Therefore, in bird sex are determined by female gametes.
