Seed _____ is when enzymes and other chemicals are activated and energy is produced to start cell division.

Answers

Seed germination happens when enzymes and other chemicals become active and energy is already produced to start cell division. Germination alone, also refers to the process wherein a plant grows from the seed. The seedling that sprouts from the seed is one of the basic example of seed germination. The growth of seeds are affected by some environmental factors such as the quantity of water, the temperature and the place where the seed is sown and of course the amount of sunlight that the seed gets is very important.

In a population of humans, the frequency of straight hair is 34 percent. If straight hair is the recessive phenotype, what is the frequency of the homozygous recessive genotype?

Answers

The frequency of the recessive phenotype is also 34%
There are 3 genotypes: Homozygous Dominant, Hetrozygous Dominant, and Homozygous Recessive. There is no such thing as Hetrozygous Recessive as a Dominant trait will express it self over a Recessive.

Lets say the letter for Curly hair is H and the letter for straight hair is h.
Now lets make a legend for the genotypes
Homozygous Dominant: HH
Heterozygous Dominant: Hh
Homozygous Recessive: hh

Since straight hair is a recessive gene and is only expressed when there is no dominant gene, the genotype for straight hair is "hh"

Therefore, the frequency of the homozygous recessive genotype which is the frequency for straight hair, is 34%

Answer:

B. 34 percent

Explanation:

I can confirm this is the correct answer because I just took the test.

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.

Which of the following cycles is crucial to living organisms? a. phosphorus b. water c. carbon d. all of the above

Answers

Answer: All of the above

Explanation:

The living component of the ecosystem consists of both living and non living components. The living components of the ecosystem consists of plants and animals.

The non-living components of ecosystem consists rocks, river, soil et cetera. The living components of the ecosystem needs to depend on the non living and living components.

The phosphorous, nitrogen and carbon cycle are important for the living components of the ecosystem.  
The answer is D. All of the above

Give three examples of stimuli that your sensory receptors are responding

Answers

Sensory receptors are cells which are able to receive external stimuli such as light, temperature and pressure. These receptors send the information they receive to the brain and it is understood as a sensation.

Examples of sensory receptors are the cone and rod cells in the retina which receive light, pressure sensors on the skin, temperature sensors on the skin, taste cells on the tongue and many more.
