Hello. This question is incomplete. The full question is:

" Which is an example of biodiversity contributing to the sustainability of an ecosystem? A meadow covers a large area of land, providing shelter to many organisms. The ocean can only support organisms that can survive salty conditions. One species of plant has been growing in a field for several years. Many kinds of fruit trees support a variety of birds and other animals in a forest.

Answer:

Many kinds of fruit trees support a variety of birds and other animals in a forest.

Explanation:

Sustainability is a concept related to sustainable development, that is, formed by a set of ideas, strategies and other ecologically correct, economically viable, socially just and culturally diverse attitudes. Sustainability serves as an alternative to guarantee the survival of the planet's natural resources, while allowing human beings and societies ecological development solutions.

Within an ecosystem, sustainability can be observed when living beings allow factors that stimulate the survival of other living beings and the conservation of environmental resources. An example of this can be seen when certain types of fruit trees support a variety of birds and other animals in a forest.

the couple is also concerned about their child inheriting hemophilia, another rare disease, which is x-linked. natalie’s brother

IgorC [24]

Hemophilia is a recessive X-linked condition and is inherited from parents. . The probability that Natalie and Daniel’s first child has hemophilia is<u> 1/4</u>, not 1/8. The statement is<u> false.</u>

<h3>What is an X-linked gene?</h3>

When talking about sex-linked genes, we refer to all those genes located in one of the sex-chromosomes and not in the somatic ones.

X-linked genes are the genes located specifically in the X sex chromosome.

Traits coded by these genes are inherited. This is, X-linked genes are transmitted from parents to children through generations.

According to this, X-linked genetic disorders will be inherited as well.

Men have a high probability of being affected since they only have one copy of the X chromosome.

In women, the effect of the mutation might be musk in heterozygous state if the mutation is recessive.

Hemophilia is a recessive X-linked disorder, which means it is coded by the recessive allele.

X+ ⇒ X chrosomosome with Dominant allele

X- ⇒ X chrosomosome with Recessive allele

<u>Genotype Phenotype</u>

X+X+ Healthy woman

X+X- Healthy carrier woman

X-X- Hemophilic woman

X+Y Healthy man

X-Y Hemophilic man

Let us make a pedigree of these families,

<u>Natalie's family</u>:

Mother healthy carrier X+X-

Father healthy X+Y

Brother hemophilic X-Y

Natalie Healthy X+X- or X+X+

Natalie has 1/2 chances of being carrier X+X- and 1/2 of being X+X+.

<u>Daniel's family</u>:

Mother healthy carrier X+X-

Father hemophilic X-Y

Sister hemophilic X-X-

Daniel Healthy X+Y

He has 1/2 chances of being healthy X+Y and 1/2 of being affected X-Y.

According to the product probability rule, if events A and B are independent from each other, the probability of occurrence of both events together is

P(A∩B) = P(A) x P(B)

In this case,

event A is Daniel being affected ⇒ 1/2
event B is Natalie being carrier ⇒ 1/2

P(A∩B) = P(A) x P(B) = 1/2 x 1/2 = 1/4

The probability that Natalie and Daniel’s first child has hemophilia is 1/4, not 1/8. The statement is<u> false.</u>

Explain how scientific theories differ from scientific laws.

Sunny_sXe [5.5K]

<h2><em>In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research</em></h2>

Which endocrine gland is responsible for the release of a hormone that stimulates T-cell development and proper immune response

Mama L [17]

Answer:

The correct answer would be d. thymus.

The thymus is a specialized lymphoid organ of an immune system.

It serves as the site for training and maturation of T-lymphocytes or T cells.

It is composed two identical lobes each containing outer region termed as cortex and inner region termed as medulla.

T-cells are first trained and selected in the cortex region via positive selection. In this, T cells which are able to bind to foreign antigens are selected and rest are degraded.

The selected T cells then move in the medulla region where they are selected by negative selection. In this, the T cells which binds to self-antigens are degraded and rest survive to become functional T cells.
