Answer:
1. Algae have a variety of adaptations that help them survive including body structures, defense mechanisms, as well as reproductive strategies. Some algae have holdfasts that attach to the sea floor and anchor them down much like roots of a plant. Many algae, such as Sargassum, have gas-filled structures called floats.
2. Algae and plants are like humans as they need food, nutrients and a good environ- ment to grow and survive. Algae make their own energy or food from the sun but they also need water, correct temperature and nutrients to grow. Algae live in water or damp environments
3. In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration

Name the two parts of the pectorial muscles.
Explanation:
Pectoralis muscle, any of the muscles that connect the front walls of the chest with the bones of the upper arm and shoulder.
There are two such muscles on each side of the sternum (breastbone) in the human body:1. pectoralis major and
2. pectoralis minor.
The organs in the human body perform specific functions for survival.
Organ A delivers blood to the body
Organ B delivers oxygen to the body
Organ C delivers messages to the body
Which of the following correctly identifies the organs that perform each function above?
Organ A is the heart, Organ B is the brain, and Organ C is the lungs
Organ A is the heart, Organ B is the lungs, and Organ C is the brain
Organ A is the lungs, Organ B is the brain, and Organ C is the heart
Organ A is the lungs, Organ B is the heart, and Organ C is the brain
Organ A is the heart
Organ B is the lungs
Organ C is the brain
Because heart only delivers blood to lungs and other body tissues, Lungs input oxygen into the blood and brain sends signals and messages to the body parts.
This is the answer. Hope it helps you

Explain how a person can be a carrier for a sex-linked disorder, but not exhibit this disorder.
A person cannot exhibit the disorder because they don't experience the condition because they have a healthy copy of the gene on their other sex chromosome.
A disorder is a functional abnormality or disturbance that affects an individual's physical, mental, or emotional health.
They have the potential to pass on the mutated gene to their offspring, but they do not exhibit the disorder themselves because they have a normal copy of the gene on their other sex chromosome.
In the case of X-linked disorders, females have two X chromosomes, while males have one X chromosome and one Y chromosome. Females can be carriers for X-linked disorders if they inherit one mutated X chromosome from one parent, and one normal X chromosome from the other parent.
Males, on the other hand, cannot be carriers of X-linked disorders because they only have one X chromosome.
Therefore, a person can be a carrier for a sex-linked disorder if they have one copy of a mutated gene on one of their sex chromosomes, but not on both.

Explanation:
Two decades after the Emerald River Dam was built, none of the eight fish species native to the Emerald River was still reproducing adequately in the river below the dam. Since the dam reduced the annual range of water temperature in the river below the dam from 50 degrees to 6 degrees, scientists have hypothesized that sharply rising water temperatures must be involved in signaling the native species to begin the reproductive cycle.
Which of the following statements, if true, would most strengthen the scientists’ hypothesis?
(A) The native fish species were still able to reproduce only in side streams of the river below the dam where the annual temperature range remains approximately 50 degrees.
(B) Before the dam was built, the Emerald River annually overflowed its banks, creating backwaters that were critical breeding areas for the native species of fish.
(C) The lowest recorded temperature of the Emerald River before the dam was built was 34 degrees, whereas the lowest recorded temperature of the river after the dam was built has been 43 degrees.
(D) Nonnative species of fish, introduced into the Emerald River after the dam was built, have begun competing with the declining native fish species for food and space.
(E) Five of the fish species native to the Emerald River are not native to any other river in North America.

The graph shows the supply and consumption of forests when the
consumption rate and population growth rate are both low.
When does consumption begin to surpass supply?
Answer:
In about 625years
Explanation:
According to the graphical representation depicted in this question, it shows the supply and consumption of forests when the consumption rate and population growth rate are both low. The green line represents the total consumption while the red line represents the total supply.
Based on observation of the graph, the total consumption exceeds or surpasses the total supply at a little above 600 years. Approximately, this can be said to be in about 625years.
Answer:
In about 625 years
Explanation:
Consumption has definitely surpassed supply by 700 years, but it only begins to surpass it around the 625 year mark according to the graph
ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.
Answer:
A
Explanation:
the sister chromatids separate
After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.
What is Homologous pair?Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.
In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.
This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.
Therefore, the correct option for this question is A.

What is a likely consequence of continued human population growth? A. More rain forests B. Fewer urban centers Ο Ο Ο Ο O C. Less pollution D. Depleted natural resources
Answer:
D. Depleted natural resources
Explanation:
If the human population on Earth continues to grow, depletion of natural resources is a very likely consequence.
Especially at the rapid rate that humans consume natural resources, continued population growth would eventually deplete them.
Fossil fuels are an example of natural resources that will eventually deplete, as humans use immense amounts of things like coal and natural gas.
Answer choices A, B, and C are incorrect because they would be consequences of decreased human population growth.
So, the correct answer is D. Depleted natural resources.

How do we make a new gene
Answer:
Well to make a new gene, theoretically you would need to mutate your DNA of some sort.
Explanation:
Genes come naturally from your parents. And if you want a new gene that you can say "control" like being tall or having a high/low metabolism, you would have to rearrange or "mess around" with your DNA.
It is believed that the ratio of cyclic electron transport to Z-scheme photosynthesis changes in response to metabolic demands. If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, how would it alter these processes compared to a plant just performing the Calvin cycle to produce glucose
Answer:
The correct answer is (b) More Z-scheme photosynthesis, less cyclic photophosphorylation
Explanation:
Z-scheme is the schematic flow of the electrons from water to NADP+ and as it connects the two different photosystems that look like z in the diagram it is termed as Z-scheme of photosynthesis. The ratio of cyclic electron transport to Z-scheme photosynthesis alters as per the metabolic requirements. In the question, it is given that If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, then it will acqiuire more z-scheme photosynthesis compared to a plant just performing the Calvin cycle to produce glucose.
Answer: More Z-scheme photosynthesis, less cyclic photophosphorylation
