How does geography influence climate?
Answer:
Geography affects the weather in many ways. ... Topographical features like mountains affect the weather mostly in the way that they direct air currents. For example, air is forced to rise over mountains. Moist air will cool as it rises, and then the clouds release the water, causing precipitation like rain or snow.

-What genotypes would the parents have to be to have a child with hemophilia?
Answer:
If the father has hemophilia and the mother DOESN'T the daughters any will have and the sons won't. If the moms have it and the dad doesn't that means all of the sons will have it and the daughters won't
Explanation:
Mark as Brainliest
Answer:
Male/Dad: XhY
Female/Mom: XHXh
Explanation:
Hemophilia is a sex-linked recessive disorder. Due to this, this means that the genotypes of those affected would be:
XhXh (female)XhY (male)Doing a quick punnet square using XhY x XHxH would equal to 25% XHXH (unaffected female), 25% XHXh (female carrier), 25% XHY (unaffected male), 25% XhY (affected male).

Why didn’t the greatest heart anatomist in history, Leonardo da Vinci, discover this simple technique that would prove that it was a pump?
Answer:
He found that the heart had four chambers and it connected the pulse in the wrist with the contraction of the left ventricle. He worked out that currents in the blood flow, created in the main aorta artery, help heart valves to close. And he suggested that arteries create a health risk if they fur up over a lifetime.
Explanation:
Leonardo da Vinci, being an anatomist, was limited by the technology and knowledge available during his time, which prevented him from discovering the simple technique that would prove the heart's pumping action.
Leonardo da Vinci lived during the Renaissance period (1452-1519), a time when scientific knowledge and understanding of anatomy were still in their early stages. While da Vinci made significant contributions to the field of anatomy, including detailed drawings and observations of the heart's structure, the concept of blood circulation.
The discovery of the heart's true function as a pump and the understanding of blood circulation came later in history, with the groundbreaking work of William Harvey in the 17th century. Harvey's detailed studies and experiments on the heart and blood vessels provided compelling evidence for the heart's role as a pump and the circulation of blood.

Before cellular division, the cell must duplicate its DNA so that the daughter cells will contain complete copies of the dna. Which characteristic of DNA makes it most suitable as a molecule for this role?
A. DNA is located in the nucleus
B. DNA is a large macromolecule
C. DNA is made of repeating sugar-phosphate subunits
D. DNA is made of two strands of complementary nucleotides
Answer:
D. DNA is made of two strands of complementary nucleotides
Explanation:
As rightly stated in this question, DNA replication must occur prior to cell division because each daughter cells must receive an equal and correct amount of genetic material (DNA). DNA replication is the process by which the DNA molecule duplicates to form two identical copies of itself.
This replication characteristics of DNA is achievable because "DNA is made of two strands of complementary nucleotides". The double-stranded DNA first unwinds into two single strands. After which, each single strand serves as a template for the new DNA strand. Two strands of a DNA molecule are complementary to one another.
Which of the following best describes a form of genetic drift in which the animal population is depleted, thereby reducing the population's genetic diversity?
A. bottleneck effect
B. disruptive selection
C. founder effect
D. gene flow
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population. So, the correct option is A.
What is the Bottleneck effect?The bottleneck effect occurs when population numbers are dramatically reduced as a result of natural disasters such as earthquakes, floods, and other natural disasters. The new population is composed of organisms that were able to survive the catastrophe whose allele frequency will be radically different from the original allele frequency.
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population.
Therefore, the correct option is A.

Explanation:
how does reducing gene flow cause speciation
Answer:
reduction of gene flow can occur due to geographical isolation too
or it can be dur to sympatric or allopatric speciation an occur.
where due to this the species are being behaviouraly isolated, and mad too reject mating due to certain reasons. Moreover mutations too can take palace causing for a genetic drift. Where the isolated species may undergo selection pressure too. So as an overall view the gene flow eventually decreases since the species diversity along with the genetic diversity decreases causing fare the reduction of the gene pool.
After many generations a new species will be formed. Resulting for speciation.

What is the positive aspect of GMO
The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
Today, those who directly see the most benefits from GMOs are farmers and agricultural companies. ... GMOs are also used to produce many medicines and vaccines that help treat or prevent diseases. Before GMOs, many common medicines had to be extracted from blood donors, animal parts, or even cadavers.

Explanation:
There are multiple positive aspects of GMO, but it has many drawbacks as well. Genetically modified foods can become more resistant to disease, pests, and even natural disasters(floods, drought, etc.)

D
A fish population is divided when a long drought causes a lake to separate into two smaller bodies of water,
Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species could lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.
