Answer:

centrosome and lysosomes

Explanation:

The centrosome (two centrioles) are only present in animal cell and is absent in plant cell. These are microtubules which are used in the formation of spindle fibres at the time of cell division. The spindle fibres seperates the chromatids. The plant cell still forms spindle fibres in the absence of centrioles.

The lysosome is absent in plant cell whereas plant vacuoles functions similarly to lysosomes. The lysosomes play important role in removing debris material from the cell. Cilia and desmosomes are also absent in plant cells.

Maksim231197 [3]

The condition in which the placenta is implanted in the lower uterine segment near or over the internal cervical  is Placenta previa.

<h3>What is placenta previa?</h3>

Placenta previa is a condition in which the placenta covers all or part of the opening to the cervical aperture, which sits at the top of the vagina, and lies very low in the uterus. One in 200 pregnancies results in placenta previa.

<h3>What is called when the placenta is attached to the uterus?</h3>

The syndrome known as placenta increta refers to the placenta's abnormally strong attachment to the uterus and subsequent embedding in the muscle wall of the organ. A disorder known as placenta percreta.

<h3>When placenta percreta occurs?</h3>

placenta percreta occurs when the placenta connects to the uterus and spreads across it, perhaps affecting surrounding organs (such as the bladder).

How do organs grow to the correct shape and size?
seropon [69]

Answer:

The size of a given axis can be changed in two ways during organ development. Cells can be rearranged first. Second, cell division orientation can be regulated. As a result, genes that control the direction of mitotic spindles may play a role in organ form.

In a sample population of people, 36% have the recessive trait of "free" earlobes (q2). What is the frequency of the dominant al
ICE Princess25 [194]

Answer:

Explanation

Given that 36% are recessive in traits

100-36 = 64% for dominant traits considering a whole population to be 100%

P=dominant allele

q= recessive allele

P2= dominant genotype

q2= recessive genotype

according to hardyweinberg principle, p+q=1

64/100= 0.64 frequency for dominant traits or genotype, therefore

p2=0.64

then

P=√0.64

p= 0.8

Therefore, dominant allele frequency (p) for the population is 0.8
