Do you think that the number of birds that are killed by wind turbines each year is acceptable? Why or why not? State your opinion and give reasons to support it. Answers must be at least three sentences.

Answers

Answer:

One of the most commonly repeated criticisms of wind power is that it kills birds. The giant spinning turbines are basically bird death traps—and often they cut through prime flying space, making the carnage even worse. At least that's the story. But how many birds really do die?

If you look around for statistics about bird deaths from wind turbines get you wildly different numbers. Some say just 10,000 birds a year

Explanation:

One of the most commonly repeated criticisms of wind power is that it kills birds. The giant spinning turbines are basically bird death traps—and often they cut through prime flying space.

What are the benefits of wind power?

The majority of wind power or wind energy is generated through the use of wind turbines. Wind power is a popular, long-lasting, and renewable energy source that has less of an environmental impact.

The process by which the wind is used to generate mechanical power or electricity is referred to as wind power or wind energy. The kinetic energy of the wind is converted into mechanical power by wind turbines.

This motion energy, or wind flow, is utilized by humans for numerous purposes: flying a kite, sailing, and even making electricity. The process by which the wind is used to generate energy is both referred to as "wind power" and "wind energy."

During which phase of meiosis do the homologous chromosomes line up across from each other in the center of the cell?

Answers

Answer: In metaphase I, homologous chromosomes line up along the center of the cell in order to be pulled apart.

Explanation:

Meiosis is the type of cell division in the germinal cells. In metaphase I of meiosis, the homologous chromosomes line up across from each other in the center of the cell.

What is metaphase I?

Metaphase I is one of the stages of meiosis I in which the duplicated homologous chromosome pairs align at the center of the cell along the midline and are connected through the centrioles.

In prophase I the homologous chromosomes are created and in anaphase I, the aligned chromosomes move towards the opposite poles so that after division each cell has the same number and equal composition of chromosomes.

Therefore, in metaphase I the homologous chromosomes are aligned at the midline.

darwin observed that organisms that were best able to survive and reproduce had adaptations that were...
A. suited to their environment.
B. ill suited to their environment.
C. incompatible with their surroundings.
D.nonexistent throughout the species.

Answers

Answer:

A: Suited for their environment

Explanation:

You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.

Hope this helped!

The Coriolis Effect shows us that when moving from the equator towards the poles, the air is moving slower than the ground below it. So, the correct option is A.

What is Coriolis Effect?

The French mathematician & physicist Gaspard-Gustave de Coriolis is honoured with the name "Coriolis Effect." It has an impact on everything from ocean currents to weather patterns to aviation transport. Despite how significant the Coriolis Effect is, few people are aware of it and even fewer actually comprehend it.

Circulating air gets deflected to the right throughout the Northern Hemisphere as well as to the left inside the Southern Hemisphere as a result of the Earth's axis of rotation. The Coriolis effect is the name given to this deflection. The Coriolis Effect demonstrates that the air moves more slowly than the ground underneath it as it travels from the equator to the poles.

Therefore, the correct option is A.

Hemophilia is an X-linked recessive genetic disorder. A baby girl is found to have inherited the trait from her parents. What are the phenotypes of the parents?

Answers

X-linked genes are inherited. The affected girl's father is hemophilic (X-Y), and the mother might be either hemophilic (X-X-) or carrier normal (X+X-).

What are the X-linked genes?

These are the genes located in the X séx chromosome and not in the somatic ones.

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 disorder 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 heter0zyg0us state.

Hemophilia is a X-linked recessive genetic disorder.

Let us represent the recessive allele with the symbol -, and the dominant allele with the symbol +.

X- is the chromosome carrying the recessive allele X+ is the chromosome carrying the dominant allele

For the affection to be expressed, the person must be either,

X-X-  ⇒   woman/girlX-Y  ⇒    man/boy

If the baby girl is found to have inherited the trait from her parents, then her genotype is X-X-. She must have received one X- chromosomes from each parent.

Her father provided the X chromosome, so he must be hemophilic (X-Y)Her mother provided the other X chromosome, but she can be either a carrier (heter0zyg0us, X+X-) or hemophilic (h0m0zyg0us recessive, X-X-).

Options,

Cross 1) affected father x carrier mother

Parentals)   X-Y    x    X+X-

Gametes)  X-      Y    X+     X-

F1) 1/2 = 50% of the progeny is expected to be healthy (25% X+X- girls + 25% X+Y boys)

    1/2 = 50% of the progeny is expected to be hemophilic (25% X-X- girls + 25% X-Y boys)

Cross 2) affected father x affected mother
