Explanation:
what do the results suggest about ways that milkweed bug populations are limited in nature?
Answer:
Temperature.
Explanation:
Temperature was the only limiting factor that controls and limits the size of the population of milkweed bug in the nature because these milkweed bug are very sensitive to temperature. Little increase or decrease in temperature can cause adverse effect to the population f milkweed bug in that environment. Milkweed bugs need food, water, space, shelter and a mate in order to survive a well as increase in population of milkweed bug.

The tap water is having a pH of 10
True or false
Answer: True
Explanation: Tap water is made slightly alkaline because acidic water could corrode metal pipes. It depends on country how high pH is. In some countries, where metal pipes are widely used pH could be even 10
Why a stent is used in the treatment of atherosclerosis in a coronary artery

A trout moves from a warm environment into a cold environment. Predict how the saturation status of hydrocarbon chains might change to ensure proper membrane fluidity in the new cold environment.
Answer:
The correct answer is - The hydrocarbons would become less saturated to increase the fluidity of the membrane
Explanation:
The ratio of saturated and unsaturated fatty acids or hydrocarbon chains is responsible for the membrane fluidity at cold temperatures. Cholesterol is an important part of membrane fluidity as it functions as a buffer, it inserts in phospholipids to preventing lower temperatures from inhibiting fluidity and at higher temperatures stabilizes the cell membrane and increase melting point and prevent increasing fluidity.
Moving from high temperature to low temperature hydrocarbon chains become less saturated in order to increase fluidity as it inserts cholesterols into phospholipids and decrease saturation.
11. Describe how the climate most likely changed between 220 million and 12 thousand years ago
Answer:
The Earth was formed about 4.5 billion years ago—that's a very long time ago! It's hard to say exactly what the Earth's daily weather was like in any particular place on any particular day thousands or millions of years ago. But we know a lot about what the Earth's climate was like way back then because of clues that remain in rocks, ice, trees, corals, and fossils.
These clues tell us that the Earth's climate has changed many times before. There have been times when most of the planet was covered in ice, and there have also been much warmer periods. Over at least the last 650,000 years, temperatures and carbon dioxide levels in the atmosphere have increased and decreased in a cyclical pattern.
These two clue show how the amount of carbon dioxide and the Earth's temperature have changed over the last 650,000 years. Both clue show a similar up-and-down pattern.
People didn't cause the climate change that occurred thousands or millions of years ago, so it must have happened for other natural reasons.

Traditional African marriage is an advantage for men only, not women
Answer:
Explanation:
Traditional marriage is an advantage to men only because they are the only ones who allowed to marry more than one wife (Polygamous) which makes women to be vulnerable. Yet the women are not allowed to be in polyandrous.
¿Cuáles de las siguientes características permite el intercambio gaseoso entre el Oxígeno (O2) y Dióxido de carbono (CO2) en los alveolos?
Answer:
Difusión y afinidad de la hemoglobina.
Explicación:
La difusión y afinidad de la hemoglobina son las características que permiten el intercambio gaseoso entre el Oxígeno (O2) y el Dióxido de Carbono (CO2) en los alvéolos. Debido a la difusión, las células de hemoglobina descargan o eliminan el gas de dióxido de carbono que es más alto en la hemoglobina en comparación con los alvéolos, por lo que el dióxido de carbono se mueve de la hemoglobina a los alvéolos mientras que, por otro lado, el oxígeno se mueve dentro de la célula de hemoglobina a través de la difusión y la estructura de la hemoglobina atraer y adherir moléculas de oxígeno consigo mismo.

Can someone help me if this is correct
Answer:
I think your answer is wrong. The right answer is D. Nucleus & Ribosome.
Explanation:
A process that takes place in the cells of all living things: the production of proteins. This process is called protein synthesis, and it actually consists of two processes — transcription and translation. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein. In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.
The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
