Answer:

Homologous structure

Explanation:

Homologous structures refers to organs or bones that have similar anatomical features found in different animals that are suggested to have the same common ancestor and serves as an evidence of evolution.

Whakes, humans and cats have similar bones in the same order but different in function.

Answer and Explanation:

The fact that whales, humans, and cats all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters or homologous structures.

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a common ancestor.

Answer:

K = 9.620 × 10⁻⁶

Explanation:

From the given information:

Temperature T= 6° C

= (273 + 6)K

= 279 K

The correct and well presentation of the reactions are:

1. Luciferin + O_2     ⇆     oxyluciferin + light   ΔG₁°

2. ATP                     ⇄   AMP + PP_i                  ΔG₂°  = -31.6 kJ/mol

The overall  ΔG° = -4.80 kJ/mol

Let's first determine the ΔG₁° for the equation (1)

ΔG° = ΔG₁° + ΔG₂°

- ΔG₁° = - ΔG° + ΔG₂°

ΔG₁° = ΔG° - ΔG₂°

ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol

ΔG₁° = 26.8 kJ/mol

Using the formula:

ΔG° = -RTIn K

In \  K =\dfrac{-\Delta G^0}{RT} \\ \\ log \ K = -\dfrac{\Delta G^0}{2.303RT}

log \ K = -\dfrac{\Delta G_1^0}{2.303RT} \\ \\ log \ K = -\dfrac{26.8 \times 10^3 \ J/mol}{2.303\times 8.314 \ J/mol/K \times 279 \ K} \\ \\ log \  K =- 5.017

K = antilog (-5.017)

K = 9.620 × 10⁻⁶

Albinism is a recessive trait in humans that is controlled by a single gene. How many recessive alleles must a person have to ha
olga_2 [115]
Answer;
Two recessive alleles are the number of alleles that a person must have to have albinism.

Explanation;
When a trait is recessive, such as albinism, an individual must have two copies of a recessive allele to express that particular trait. Recessive alleles are denoted by a lowercase letter , such as b versus B. Only individuals with a bb genotye will express a recessive trait, hence, the offspring must receive one recessive trait from each parent to exhibit the recessive trait.
