Answer:
Explanation:
Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
what is responsible for pumping blood to the lungs?
The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.
2. What are examples of cold blooded organisms? 3. How do cold blooded organisms behave when it's cold outside? Why?
Answer:
Cold blooded organisms are mostly reptiles, like lizards, for instance. Cold-blooded animals are able to survive when it is cold, and they behave as they normally would. Some animals, such as alligators, will lie in the sun at an attempt to warm themselves. They behave like this because just like us, they are just organisms trying to live their lives.

What are 4 ways mutations affect protein structure.
Answer:
Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly.
Explanation:
Germline mutations occur in gametes. Somatic mutations occur in other body cells.
Chromosomal alterations are mutations that change chromosome structure.
Point mutations change a single nucleotide.
Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame.

HELP ASAPIf the following mRNA strand were produced during transcription, what amino
acids would be found in the
protein?
CAUGGUGGCUACGGG
The table below shows which amino acid results from each codon.
• A. Histidine-glycine-glycine-glycine
• B. Glycine-histidine-histidine-tyrosine-histidine
• C. Glycine-histidine-glycine-glycine
• D. Histidine-glycine-glycine-tyrosine-glycine
Answer:
D
Explanation:
To translate mRNA to protien you start at the beginning of the strand and read the first 3 letters then identify which amino acid it is by looking at the chart. You repeat this process until you have reached the end or until there are no more pairs of 3 letters.
So we have the strand CAUGGUGGCUACGGG
the first the letters are CAU
if we look at the chart CAU corresponds to Histlidine
Repeating this process with the rest of the mRNA strand we should get
Histidline - Glycine - Glycine - Tyrosine - Glycine
the answer is D.

2 Humans have been selectively breeding corn for generations. During the process
of domestication, the wild form of corn was eventually changed into a form that
has more favorable traits.
Early farmers most likely used corn seed that had -
A thin stalks to withstand stronger wind.
B a darker color so that they would blend with the field and be protected from
predators.
Clarger leaves that could be used for compost.
D the ability to grow in a large number of climates, soil types, and produced
the largest amount of kernels.
Pretty sure it's D because A and C wouldn't help the corn survive. I don't think B would make sense either.
The ability to grow in a large number of climates, soil types, and produced the largest amount of kernels since these traits would have been the most favorable for food production. Therefore, option (D) is correct.
What is selective breeding?Selective breeding is the process of intentionally choosing and mating organisms with desirable traits in order to produce offspring with similar or improved traits.
This process has been used by humans for thousands of years to improve the quality and productivity of domesticated animals and plants. Selective breeding involves identifying desirable traits such as increased yield, resistance to disease or pests, and improved growth or reproduction, and then selectively mating organisms that exhibit these traits.
Over time, this can lead to the development of new varieties or breeds with the desired characteristics. While selective breeding can lead to significant improvements in agricultural productivity, it can also raise concerns related to genetic diversity and potential negative impacts on animal welfare.

Which of the following describes family size since the eighteenth and nineteenth centuries?
1. Families are having less children today.
2. More families have adopted rural lifestyles.
3. Families are larger today because they are less expensive to raise.
4. Family size has stayed relatively the same over the past few centuries.
Answer:
1.
Explanation:
The statement which describes family size since the eighteenth and nineteenth centuries is families are having fewer children today. Therefore, the correct option is A.
Due to a number of social, economic, and cultural changes, such as improvements in health care, easier access to contraception, changes in social standards, and changes in family responsibilities and dynamics, family size has generally decreased over the past few centuries. As a result, the average family size in many parts of the world is now smaller than it was in previous centuries.
Therefore, the correct option is A.

Explain which fossils would be newer and older in the various layers of rock in the Grand Canyon?
Answer:
the fossils found in a upper layers then those fossils will be newer and the older ones would be on more lower layers
The youngest of Grand Canyon's rock layers, the Kaibab Formation, forms the rims of the canyon and is a mere 270 million years old.
What kind of fossils are found in the Grand Canyon?The most common fossils are small sea creatures, such as brachiopods, bryozoans, coral, and crinoids. Combined with the sandstone, this tells us that the region was a warm, shallow sea when these sediments were deposited. A key feature of the Grand Canyon is, unsurprisingly, the canyon itself.
What are the oldest rocks in the Grand Canyon?The oldest rocks in Arizona are the Vishnu Basement Rocks exposed in the Upper Granite Gorge, Grand Canyon. The Brahma Schist, part of these basement rocks, is about 1.75 billion years old.
