what is it called when energy is required to move materials through a cell membrane ?
Answer:active transport
During active transport, ATP is required to move a substance across a membrane, often with the help of protein carriers, and usually against its concentration gradient. One of the most common types of active transport involves proteins that serve as pumps.

How do the circulatory and nervous systems work together to maintain homeostasis | ASAP
Answer:
The circulatory and the nervous systems work together to maintain homeostasis because the circulatory system gives your brain a lot of oxygen and glucose while your brain regulates your heart rate and blood pressure. Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain homeostasis.

Cytokinesis – division of the cytoplasm resulting in two identical d_______________ cells.
Answer: daughter
Explanation: Cytokinesis results in the division of cytoplasm in a parental cell, creating 2 identical daughter cells.
Hope this helps!
Cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.
What is the significance of cytokinesis in mitosis?It is very important in mitosis because it aids in the division of two cells from one cell during the cell division process and results in the formation of two genetically identical daughter cells; without cytokinesis, the chromosomes would remain in the same cell, resulting in mutation as multinucleated cells are formed in such a process.
Hence, cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.

Answer:
Genetic variation is the difference in DNA among individuals or the differences between populations. There are multiple sources of genetic variation, including mutation and genetic recombination.
Explanation:
Explanation:
Genetic variation refers to diversity in gene frequencies. Genetic variation can refer to differences between individuals or to differences between populations. Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.
True or false: Plants release oxygen by taking CO2 and sunlight?
Answer:
True
Explanation:
Answer:
Yes this is true
Explanation:
13. In a forest, why do you rarely see young pine trees growing under a broad-leaved tree, such as a maple? If broad-leaved trees eventually take over a forest as pines die off, how does that affect other organisms living in the forest? How does it affect this forest ecosystem?*
Answer:/Explanation:
Broad leaved trees would block the sunlight due to the size of their leaves. This would reduce the amount of sunlight that the pine tree could absorb, and would therefore inhibit its ability to efficiently perform photosynthesis. This would reduce the amount of food it could synthesise, and interfere with its growth and reproduction.
Without pine trees, the diversity of the ecosystem would be reduced. Several organisms rely on pine seeds and leaves as a food source. In the absence of pine trees, competition for other food sources could increase, and certain birds, squirrels etc. could die off.
Pine trees are also a habitat for many birds and small creatures. Without these trees, these animals could struggle to find efficient shelter.

Which of the following is Bernoulli's principle?
1. As the speed of a moving fluid increases the pressure within the fluid decreases.
2. As the speed of a moving fluid decreases the pressure within the fluid increases.
3. As the speed of a moving fluid increases the pressure within the fluid increases.
4. As the speed of a moving fluid decreases the pressure within the fluid decreases.
Answer:
1. As the speed of a moving fluid increases the pressure within the fluid decreases.
Explanation:
Hope this helps!
The Bernoulli's principle is applied when the speed of a moving fluid increases as the pressure within the fluid decreases. Thus, the correct option is 1.
What is Bernoulli's Principle?The inverse relationship between pressure and speed at a point in any fluid is called Bernoulli's principle. Bernoulli's principle states that "At points along a horizontal streamline, higher pressure regions have lower fluid speed and lower pressure regions have higher fluid speed".
Bernoulli's principle is based on the law of conservation of energy. The total energy (pressure energy, potential energy and kinetic energy) of a flowing liquid under constant pressure at different points differ.
Therefore, the correct option is 1. With the increase in speed, the pressure within the fluid decreases.

Alyssa is observing two cells, X and Y. Each cell is from either a plant or an animal. She records some of her observations in a chart.
Cell Observations
Cell X Cell Y
has lysosomes lacks lysosomes
lacks a cell wall has endoplasmic reticulum
has ribosomes has a nucleus
Which additional observation will Alyssa most likely make?
Cell X has a cell membrane, and Cell Y does not.
Cell Y has a cell membrane, and Cell X does not.
Cell Y has a larger vacuole than Cell X.
Cell X has a larger vacuole than C
Answer:
Cell Y has a larger vacuole than cell X
Explanation:
Cell Y is the plant cell, only plant cells have a tough and rigid cell wall, animal cells do not. The observation that Cell X lacks a cell wall as well as having lysosomes is indication that Cell X is an animal cell. The answer that Cell Y has a larger vacuole is true because plant cells need to store more water and nutrients than animal cells and will have a much larger vacuole.

B-Weak genetic similarities in closely related organisms and strong genetic similarities in distantly related organisms.
C-Strong physical similarities among closely related organisms and also among distantly related organisms.
D-Weak physical similarities among closely related organisms and also among distantly related organisms.
Answer:
B. Weak genetic similarities in closely related organisms and strong genetic similarities in distantly related organisms
Explanation:
just took the quiz
Weak genetic similarities in closely related organisms and strong genetic similarities in distantly related organisms will be an evidence against existence of evolution.
What are the evidence for evolution?The evidence for evolution of species include similarity in the DNA of closely related species as well as similar structural and anatomical features.
Therefore, an evidence to prove that evolution does not exist will be weak genetic similarities in closely related organisms and strong genetic similarities in distantly related organisms.

Answer:
With the boost in warmer weather and excess water, populations will boom
Explanation:
Yabbies will do best at a water temperature of between 12°C and 20°C but they will tolerate water that is a little colder or warmer. Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water. With the water needed for breading and warmer weather used for breeding, population numbers for the Yabbies should rise.

Why are the tais pointing inward in layer H
Answer:
Because they are hydrophobic
Explanation:
The image shows a cell membrane, which is made up a phospholipid bilayer. The phospholipid bilayer is made up of a phosphate head, which is hydrophillic, and fatty acid tail, which is hydrophobic. That means they are repelled by water.
Because the tails are hydrophobic, they are repelled by the water towards one another, while the heads remain facing outwards,

Sickle cell anemia is a genetic disease that affects the red blood cells. Your red blood cells are typically donut shaped
and have the job of carrying oxygen around your body. In people with sickle cell anemia, the blood cells become
crescent-shaped and are thick and sticky. They are not as able to carry oxygen, and can even get clogged in the blood
vessels blocking the flow of blood, and therefore oxygen to organs, causing pain and organ damage.
Sickle cell is caused by a genetic mutation that changes a single glutamic acid to valine in the 6 th amino acid position.
Examine the codon chart provided above (for #s 3-5), and determine what mutation likely occurred to cause the
change from glutamic acid (GLU) to valine (VAL). To help get you started, it is helpful to know that a person with
NO sickle cell at amino acid #6 has a DNA code of CTC. (4pts)
