Make 2 full sentences using the scientific term "homoozygous" and 2 full sentences for "heterozygous (Side note: i had to add an extra O to the first thing so its not considered a offensive word-Thank you for your help!)
im getting really annoyed i have posted this 2 times and bots keep answering and ruining it lol
Answer:
1. If you have two copies of the allele for brown hair, you are homoozygous for that trait.
2. If you have two copies of the allele for brown hair, you are homoozygous for that trait.
3. Since sickle cell disease requires two alleles that are alike, a person with a heterozygous would not have the disease.
4. If both gene alleles are different, the organism is heterozygous for that particular trait.
Change the "homoozygous" in the sentences

Genetics yo,
How do the roots and stem take part in the transport of water in a plant?
please make a good explanation and make long answer pls! thanks :D
Answer:
The roots take part in the transport of water in a plant by absorbing water from the ground. The stem moves the water to the rest of the plant.
Explanation:
When a plant is in wet soil, the roots absorb the water from the ground and carry it to the stem. Then, the steam acts as a passageway and the water goes up the steam, and into other areas of the plant, sucks as leave, and (if the plant has them) flowers.
I hope this answer works, and that it's not late.
Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.
30, 26, 25, 11, 34, 20, 26, 26
a.
Mean = 99
Median = 26
Mode = 26
c.
Mean = 24.8
Median = 34
Mode = 26
b.
Mean = 24.8
Median = 26
Mode = 25
d.
Mean = 24.8
Median = 26
Mode = 26
Please select the best answer from the choices provided
A
B
C
D
Answer:
D.
Mean: 24.8
Median: 26
Mode: 26
Explanation:
The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.
30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198
Now, we divide by how many numbers we started out with (8).
198 divided by 8 = 24.75, rounded would be 24.8
To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:
11, 20, 25, 26, 26, 26, 30, 34
As you can see, the middle number is 26.
To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.
11, 20, 25, 26, 26, 26, 30, 34
As you can see, the number 26 appears the most often.
So, we end up with:
Mean: 24.8
Median: 26
Mode: 26

The red dots represent oxygen molecules in this diagram. This diagram shows __________.
facilitation diffusion
osmosis
diffusion
exocytosis
endocytosis
The correct answer is option B.
Diffusion is the process of movement of both the solute and solvent. the characteristic of diffusion is that it does not require a membrane or a layer separating two parts. In diffusion particles or solutes move from a region of higher concentration to a region of lower concentration.
In the example, we can see that red particles are together in a place and after some time they get distributed evenly in the entire liquid. This process is known as diffusion as it does not require a membrane.

make 2 full sentences that use "Hoomoozygous" and another 2 full sentences for "heterozygous" (i couldnt use the proper spelling for hoomoo because its considered in a hoomoophobic slur thing even though its also a scientific term"
Thank you! and I hope you have a great day :)
Answer:
To be Hoomoozygous means you've inherited two of the same genes. If you've inherited freckles then you have Hoomoozygous genes.
To be Heterozygous is to have two different genes. If you have a recessive gene and a dominant gene then you have Heterozygous genes, because they are both different.

Use the information to answer the following question.
The Blacklegged Tick is a parasite of the White-Footed Mouse. The White-Footed Mouse carries the bacteria which cause Lyme Disease. The bacteria are spread to ticks that bite infected mice. If an infected tick then bites a human, the human can be infected with the bacteria and develop Lyme Disease. Scientists have proposed that increased human development has led to an increase in the White-Footed Mouse population which can lead to increased cases of Lyme Disease in humans.
Answering which scientific question would BEST support the scientist’s hypothesis?
A.
Do White-Footed Mice live in forest areas?
B.
Does Lyme Disease spread to humans from ticks?
C.
Do ticks bite a mouse more than once?
