Let's use red hair for example - r

And we'll say that brown hair is dominant - R

You won't get red hair from RxR, the gene isn't in the punnet square. (Not A.)

Rxr would be always be Brown hair and they carry the red hair gene. (Not B.)

The dominant gene is the opposite of the recessive trait. (Not C.)

What needs to change so that only the green solutes diffuse across the membrane?

Answers

Diffusion is a process which allows particles to move from areas of high concentration to areas of lower concentration. The process requires that particles are moving. As long as particles are not at a temperature of 0K (absolute zero) they have kinetic energy (energy of movement).

What need to be changed is ; The use of selectively/semi-permeable membrane

To selectively allow the passage ( diffusion ) of a certain type of solute through a membrane in a solution, we should make use of a selectively permeable membrane which allows only the passage of a certain type of solute contained in the solution ( like the green solutes ).

The use of permeable membrane in a solution is to selectively allow flow of solutes or solvent from a region of lower concentration to a region of higher concentration.

Hence we can conclude that what needs to be change is The use of selectively/semi-permeable membrane will allow only the green solutes to diffuse across.

Why is it important to center the object you want to look at in your field of view before changing to a higher magnification objective lens? A. So the object is still in your field of view at the higher magnification. B. So you can always see the entire object at the higher magnification. C. So you do not damage the higher magnification objective lens.​

Answers

Answer:

B. So you can always see the entire object at the higher magnification

Explanation:

A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.

However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.

infection does Fernanda have?
bacterial
fungal
none of the above
viral

Answers

Answer:

bacterial

Explanation:

A prokaryotic organism is an organism that does not possess a membrane-bound nucleus that houses its genetic material. Organisms grouped under this domain are bacteria, archaebacteia etc.

According to this question, Fernanda goes for a blood sample because she felt sick. The result of the blood sampling shows that the cells of Fernanda contain a pathogen that seems to be made of small cells with no nucleus. This property describes a prokaryotic pathogen. Hence, the infection is most likely to be that of a BACTERIAL INFECTION.

Note that, a fungus is eukaryotic while a virus is considered non-living because it can only replicate in a living host.

I can't definitively answer this because I don't know the experiment, but I can help.

Explanation:

The "control group" of an experiment is like a dry simulation, where there is no variables changed across all the different trials you do. This is different from a dependent variable or an independent variable. Using your newfound knowledge of what a control group is you can automatically cross off the last option.

Since I cannot see what your experiment was I can't give you which of the top 3 answers it is however. You need to look at which one has no change.

If I were to blindly guess I would say the top option seems like the most likely answer.

Nonnative species can cause serious problems with marine ecosystem biodiversity. The graph shows a summary of the different methods by which invasive species reach new locations based on United States Geological Survey data as of 2016. Based on this information, what recommendation could be made to reduce introductions?

A- Methods should be put in place to reduce the ability of species from escaping from captivity and establishing themselves in new locations.

B- People should take extra care when setting up a home fish tank to be certain that all organisms in it will be properly maintained so that the animals remain healthy and diseases are not spread.

C- Science should more closely study the genetics of the different organisms used to prevent mixing of DNA.

D- Ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.

Answers

Answer: D

Explanation: 20% of invasive species are introduced by Shipping so checking the ballast tanks in cargo ships would help the most I think

To reduce introductions of Non-native species, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and also check for unintended cargo.

What are non-native species?

Non-native species are also called invasive species. They are called so as they are foreign or not indigenous to a particular ecosystem and have been introduced to the said ecosystem by some unnatural methods.

These species show a high capacity for adaptation to their new environment. They quickly multiply and reproduce and therefore increase in population.

This sudden and unnatural increase in their population soon after they are introduced to a new environment will greatly affect the ecosystem of the new environment. The new species will compete with the native organisms of that environment for resources. This may cause the native flora or fauna to become endangered or even extinct.

The accidental introduction of invasive species happens quite often and causes a lot of problems. In a marine ecosystem, it happens a lot due to the ships that travel through a variety of marine regions.

So, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.

Therefore, the correct option is D.

Find the area plz plz Science Mysteries: Why Do People Yawn?Science has given humans many amazing devices and useful bits of knowledge. We know so much about our bodies and how to stay healthy, for example. We also know how to make machines and devices that make life easy for us. Scientists dedicate their lives to knowledge, but even with a lifetime commitment, sometimes scientists fail to find all the answers. One mystery that still remains unsolved is why we yawn-what makes us yawn and what purpose it serves.Recent studies suggest that we yawn when we get tired as a way to encourage our brains. The theory is that yawning helps cool the brain, allowing it to work more efficiently. According to WebMD's article about these studies, when you yawn, your jaw muscles get stretched, increasing blood flow to your neck, face, and head. Also a deep breath during the yawn forces spinal fluid and blood down from the brain. The cool air then cools down these fluids.Other scientists believe, however, that yawning is a form of communication. This theory attempts to explain why yawning seems to spread from person to person. This kind of behavior is called "contagious yawning" and carries with it a possible social message. Scientists are not yet sure what exactly the message is, but they believe people who have more social empathy are more likely to start yawning when they see someone else yawning.Scientists will continue to investigate the mystery of the yawn. Is it a leftover behavior from before humans had language? Was it a "Hey, I'm sleepy. Let's go to sleep" message? Or is it really just a way to keep our brains cool? While this behavior still is largely a mystery, one thing is certain: you are probably fighting the urge to yawn right about now.Which word from the text best describes scientists' understanding of the yawn?(5 points)Question 1 options:1) Mystery2) Breath3) Language4) Message im in the middle of an English test will someone pls help me What is the minimum value of h(x)?h(x) = (x - 5)^2 + 6 What the answer to this question now now can some please answer it.
