Answer:
No, it's dominant.
Explanation:
It is an autosomal dominant genetic disorder and is not a chromosomal disorder.
Answer:
NO!
Explanation:
It is an autosomal dominant genetic disorder and is not a chromosomal disorder. Turner syndrome (TS), sometimes referred to as congenital ovarian hypoplasia syndrome, is a genetic disorder.

In the lab activity, you will use a chemical called a pH indicator that changes color as the pH of a
solution changes. If you added a pH indicator to two different solutions and they both turned the
same color, what would this tell you about the pH of each solution?
ph indicator is used to find the acidic or basic nature of a mixture.
there is a range of colours from red to blue
red colour indicates that solution is acidic and blue colour indicates that solution is basic
if two solutions have same colour that means they also have same ph value
What are the phenotypes of an organism?
A. the organism's genes
B. the organism's physical traits
Answer:
A.
Explanation:
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
Answer:
A. the organism's genes
Explanation:
The phenotypes of an organism are the genes carried by the organism.

Explain in at least five sentences what you've learned about how
global warming and climate change are impacting our Earth in different regions of the world.
Explanation: I'd first address the issue as a whole and explain the meaning and the general impacts of climate change, then use a variety of different places. For example, global warming causes the ice caps to melt in Antarctica. Then, explain how this has an impact on the environment meaning that polar bears could be in life-threatening situations and possibly even become extinct in the future which has a further impact on other animals in that food chain and ecosystem. This is just one example. You could also explain the unbearable heat in countries nearer the equator, which prevent crops from growing; the sea levels rising; or extreme weather events like huge flooding or heatwaves. It depends what you have learnt about in class, but I'm assuming it would be about this sort of thing.
Answer:
Higher death rates. ...
Dirtier air. ...
Higher wildlife extinction rates. ...
More acidic oceans. ...
Higher sea levels.

What best defines gene flow
Explanation:
Gene flow is the exchange of alleles between two or more populations.
Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur

can anyone help me with this question? Thank you.
Answer:
At B part.
Explanation:
At B part the nightfall will happen first because the B part is in the shade and will not present in front of the sun. When the earth rotates its own axis, the shaded part which is B comes in front of sun which means day time is started while on the other hand, the A part is in the shade and will experience nightfall so we can say that the nightfall occurs at B part of the earth.

Fungi live by
A. Making their own food.
B. Eating other organisms.
C. Sucking up nutrients made by other organisms.
Answer:
C
Explanation:
Fungi are heterotrophic.
Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi feed by absorption of nutrients from the environment around them. Most fungi are saprophytes, feeding on dead or decaying material.
Answer:
C. Sucking up nutrients made by other organisms.
Explanation:
Fungi (singular: fungus) are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs (cannot make their own food) and have important roles in nutrient cycling in an ecosystem.
It could be other plants or animals where they get a great place to source their food.
During this time, the fungi kind of hibernates until they get a suitable and beneficial place they can transfer to.

An invasive species doesnt grow slowly, they do the opposite they grow super fast becaus ethey are the best out of the others and completly own the place.
The can adapt or they aren't considered invasive, that's why they are so effective
They aren't endangered or else its not invasive, they are thriving because they have 0 competition.

Because of their capacity for rapid growth and reproduction, or because their new environments are devoid of any native predators or pests, invasive species frequently thrive in their new ecosystems. Thus, option B is correct.
What is a characteristic of invasive species?An invasive species doesn't develop slowly; on the contrary, they accelerate their growth because they are superior to all other species and have taken over the area completely.
Because of this, invading species may pose a threat to native species and interfere with crucial ecosystem processes.
A species must be easily adaptable for it to be invasive. It needs to multiply swiftly. It must result in harm to local property, the local economy, or the local fauna and flora. Accidental introduction of invasive species into a new area is common.
They are so successful because they can adapt and aren't intrusive. Because they have no competition, they are thriving while not being threatened.
Therefore, They take resources from native species.
