Cellular respiration happens in all eukaryotic cells and it occurs in the mitochondria, the powerhouse of the cell. cell resp breaks up glucose in order to create more ATP for the cell. the products that go IN are GLUCOSE and OXYGEN. the products that come OUT are CARBON DIOXIDE, WATER, and of course, ENERGY.

Which type of joint do you think allows for the greatest number of different movements? Explain your reasoning.

ella [17]

Answer:

Ball and socket joint.

Explanation:

In simple words a synovial joint is a type of joint which articulates two bones and also allows movement. Six types of synovial joints occur in our body at different locations. Ball and socket joint is one of that six types of joints. It is the joint which allows maximum movement of the joining bones because this joint is formed when one bone has a spherical end like a ball and the other bone covers this ball with a cup like structure called socket. Due to such arrangements of bones the joining bones can be moved in any direction and also they can be rotated to some extent.

pantera1 [17]

Answer:

1.2 million plants and animals

Explanation:

The living organisms have been grouped into two kingdom

a) Plants

b) Animal

Earth has enormous varieties of living species ranging from microscopic bacterias to huge animals like elephants, rhinoceros, from water plants and animals to terrestrial plants and animals , from autotrophic to heterotrophic organisms, from forest biome to desert biome etc.

In totality, there are 8.7 million species of plants and animals on earth. But till today only 1.2 million species have been identified and described.

In some breeds of mice, yellow coat color is

Elis [28]

In the exposed lethal genes cause the individual's death during embryionic development before being born. H0m0zyg0us dominant individuals do not get born. Yellow: 2/3. Grey: 1/3. Phenotypic ratio: 2:1

<h3>What is complete dominance?</h3>

When the dominant allele completely masks the expression recessive allele, we talk about complete dominance.

This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait.

The dominant allele is hiding the expression of the recessive allele.

<h3>What are the lethal genes?</h3>

Refer to genes that impede the normal development of the individual.

They can cause death during embryo development before the individual gets born,

They can cause the individual's death after being born and before reaching sèxual maturity.

Let us assume that mice color is coded by a single diallelic gene that expresses complete dominance.

Available data:

Yellow color is dominant over grey color.

Yellow is coded by the dominant allele Y
Grey is coded by the recessive allele y

Genotype YY → Yellow and lethal

Genotype Yy → Yellow

Genotype yy → Grey

The cross would be as follows,

Cross: Yy x Yy

Gametes) Y y Y y

Punnett square) Y y

Y YY Yy

y Yy yy

F1) Considering ONLY the successfully born individuals

Genotype

2/3 = 50% of the progeny is expected to be heter0zyg0us, Yy.

1/3 = 25% of the progeny is expected to be h0m0zyg0us recessive, yy.

Phenotype

2/3 = 50% of the progeny is expected to be yellow, Yy.

1/3 = 25% of the progeny is expected to be grey, yy.

The phenotypic ratio is 2:1
