Which structure or organelle is found in both prokaryotic and eukaryotic cells? A) ribosomes B) chloroplasts C) mitochondria D)

rjkz [21]

Answer:

The correct answer would be A) ribosomes.

A ribosome is a vesicular structure present in both prokaryotic and eukaryotic cells. They consist of ribosomal RNA and associated proteins.

They are the site of translation in both prokaryotic and eukaryotic cells.

They are made up two units which are called large sub-unit and small sub-unit.

In prokaryotic cells, 70S ribosomes are present which are made up of 50S large sub-units and 30S small sub-units.

In eukaryotic cells, 80S ribosomes are present which are made up of 60S large sub-units and 40S small sun-units.

How does salt kill snails?

AVprozaik [17]

Salt works to kill slugs by using the osmosis they depend on to survive to dehydrate them of the water that is within their body. Slugs depend on osmosis because they pick up water from areas surrounding them to hydrate themselves.

Dino and his family live in a community where people just throw their garbage anywhere. Recently, Dino was hospitalized due to d

jok3333 [9.3K]

Answer:

The main measure that must be taken to alleviate this situation is the proper disposal of garbage in the community in which Dino lives.

Explanation:

Inadequate disposal of garbage can cause a series of very serious illnesses and accidents to the entire community, which reinforces the need for all residents of a community to promote the proper disposal of waste. This is not happening in the community where Dino and his family live.

The inadequate disposal of garbage can contaminate the water and food of the community, causing diarrhea in Dino. This garbage also caused the accumulation of standing water, allowing the dengue mosquito to develop and infect his sister. In addition, garbage has created a suitable environment for maleficent microorganisms, such as the bacteria that causes tuberculosis.

A grow seeded purple flowered heterozygous plant (YyPp) is crossed with a green seeded, white flower plant (yypp). What is the p

vredina [299]

Question:

A yellow seeded, purple-flowered heterozygous plant (YyPp) is crossed with a green seeded, white-flowered plant (yypp).

(Y = yellow seed allele; y = green seed allele; P = purple flower allele; p = white flower allele)

What is the probability that an offspring of this cross produces plants with green seeds and white flowers? Assume the traits assort independently.

Answer:

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25

Explanation:

Available data:

Y = yellow seed allele; Dominant
y = green seed allele; Recessive
P = purple flower allele; Dominant

p = white flower allele; Recessive
the traits assort independently

Cross: A yellow seeded, purple-flowered heterozygous plant with a green seeded, white-flowered plant

Parentals) YyPp x yypp

Gametes) YP, Yp, yP, yp yp, yp, yp, yp

Punnett square)

YP Yp yP yp

yp YyPp Yypp yyPp yypp

F1) 4/16 = 1/4 = 25% YyPp, Yellow seeds and Purple flowers

4/16 = 1/4 = 25% Yypp, Yellow seeds and white flowers

4/16 = 14 = 25% yyPp, green seeds and purple flowers

4/16 = 1/4 = 25% yypp, green seeds and white flowers.

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25
