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.

Answers

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.

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.

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?*​

Answers

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.

The phenotype of the offspring gives details about which trait is dominant and which trait is recessive.

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 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

Answers

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.

How do the circulatory and nervous systems work together to maintain homeostasis | ASAP

Answers

The cardiovascular system helps maintain homeostasis by continually supplying the central nervous system--the brain and spinal cord--with oxygen and glucose. Brain cells start dying after just one minute without oxygen. The brain is the control center for all of the body's homeostatic processes.

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.

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)

Answers

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.
