Which statement about vacuoles is true?

Answers

where is the statement?

Bacteria and archaea differ in____ a.whether they have a nucleus.. b.the makeup of their cell walls.. c.size.. d.whether they have a cell wall.

Answers

The answer is b.the makeup of their cell.

Both bacteria (which belong to the group of Prokaryotes) and Archaea have no nuclei but have cell walls. Those are groups of unicellular organisms. But, they differ in the makeup of their cell walls. Archaea have cell walls made of uncommon lipids while bacteria have cell walls made of peptidoglycan.

Bacteria and archaea differ in their cell walls makeup.

Further Explanation:

Archaea is considered to arise many years ago and is also considered to be the most primitive form of life. Earlier they were classified as bacteria but as they possessed certain difference features when compared with bacteria, it was now termed as archaea. Some of the characteristics of archaea resembles eukaryotes while other resembles with prokaryotes.

Archaea are single celled organism and they can thrive in harsh conditions like marshy area and hot springs. Some of the example of archaea are, Thermococcus litoralis, Methanopyrus kandleri, Cenarchaeum symbiosum etc.

The features of archaea which are similar to bacteria are:

1. Lack of nuclear envelop.

2. Lack of membrane bound envelop.

3. Presence of circular chromosomes.

The features of archaea which are similar to eukaryotes are:

1. Methionine is the initiator amino acid for protein synthesis.

2. Lack of peptidoglycan in their cell wall.

3. Association of histones with DNA.

Organisms that live in desert and desert-scrub biomes have developed unique adaptations that aid in their survival. The Sahara Desert takes up ten percent of the continent of Africa, and is the largest desert in the world. The species that live in the Sahara are highly adapted to survive in the extreme conditions they live in. What morphological and physiological adaptations might be seen in the organisms that live in the Sahara Desert?a.

water absorbing skin, large eyes for hunting at night, webbed feet

b.

light colored fur or feathers for camouflage, dense layer of fat and fur for warmth, hibernation during cold months

c.

small bodies and long limbs in warm-blooded organisms, light colored fur or feathers to reflect sunlight, lack of sweat glands in many organisms, hibernation during hot months

d.

dark colored fur or feathers for heat absorption, large bodies and short limbs, consumption of primarily scrub and short grasses

Answers

The morphological and physiological adaptations that might be seen in the organisms that live in the Sahara Desert are small bodies and long limbs in warm-blooded organisms, light colored fur or feathers to reflect sunlight, lack of sweat glands in many organisms, hibernation during hot months.

Best answer choice: C)

I hope it helps, Regards.

The answer is c. small bodies and long limbs in warm-blooded organisms, light colored fur or feathers to reflect sunlight, lack of sweat glands in many organisms, hibernation during hot months.

In the Sahara desert, a temperature could reach extreme values. It is extremely hot and sunny and animals must adapt in order to survive in such conditions.
The warm-blooded animals have small bodies and long limbs. The aim of longer limbs is to increase surface area through which body heat will be lost to the environment. Fur of feathers are light colored because lighter colors reflect the sunlight more efficiently. It is known that black color the most efficiently of all colors absorbs heat while white color most efficiently of all colors reflects the sunlight. Further, animals lack in sweat glands. If they do not sweat, less water will be lost from the body. Also, many species hibernate during hot months and thereby save energy.

Describe the process of fertilization

Answers

Answer:

Explanation:

Fertilization is the process by which haploid gametes (n- sperm and egg) fuse together to form a diploid cell called ZYGOTE. A gamete is a reproductive or sex cell produced by a sexually-reproducing organism during meiosis. Diploid organisms produce gametes that contains one set of chromosomes i.e haploid. Male organisms produce sperm while female organisms produce egg/ovum.

To ensure that the zygote, which grows into the full organism, has the correct number of chromosomes, only one sperm can fuse with one egg. It is worthy to note that, fertilization can either occur internally (union of sperm and egg within the body of the female parent) or externally (joining of gametes outside the body).

The sperm plasma then fuses with the egg's plasma membrane, the sperm head disconnects from its flagellum and the egg travels down the Fallopian tube to reach the uterus. In vitro fertilization (IVF) is a process by which egg cells are fertilized by sperm outside the womb, in vitro.
