Use Figure 1 to evaluate each trigonometric function of angle A . The side adjacent to angle A has length 8 and the side opposite angle A has length 10.
Answers
The trigonometric ratios are;
Sin A = 0.78Cos A = 0.625Tan A = 1.25What are the trigonometric ratio?The trigonometric ratios are sine, cosine and tangent. Now we have the hypotenuse of the triangle. Figure 1 has been shown in the image attached to this answer.
c = √8^2 + 10^2
c = 12.8
sin A = 10/12.8 = 0.78
Cos A = 8/12.8 = 0.625
Tan A = 10/8 = 1.25

would you expect a plant to produce more oxygen on a cloudy day or a sunny day? explain
Answers
Answer:
You would expect a plant to produce more oxygen on a sunny day because there are more sun rays available to plants so photosynthesis is easier to maintain, as well as oxygen production.

O current power and ocean thermal energy
Answers
Answer:
I don't unerstand the question
Explanation:
I think it's B
Answer:
Tidal power and current power
Explanation:
First, we can determine that A and B are obvoiusly wrong. Ocean thermal energy produces zero carbon emissions, as most forms of hydroelectric power do. Secondly, wave energy might affect aquatic life, but it wouldn't affect the migration of birds. After reviewing the 3rd and 4th answers, they do look reasonable. Therefore, your answer is tidal power and current power.

Are the members of the third generation still carriers/affected by the trait? How many
percent are affected by the trait?
Answers
Answer:
When a genetic disorder is diagnosed in a family, family members often want to know the likelihood that they or their children will develop the condition. This can be difficult to predict in some cases because many factors influence a person's chances of developing a genetic condition. One important factor is how the condition is inherited. For example:
Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent. However, in some cases an autosomal dominant disorder results from a new (de novo) mutation that occurs during the formation of egg or sperm cells or early in embryonic development. In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.
Can someone help me understand interphase, prophase, metaphase, anaphase, and telophase
Answers
Answer:
They are all stages of mitosis, which is cell division (for new cells for repair and growth)
interphase- the longest stage of the process. The DNA in the chromosomes copies itself, ready to split for mitosis. ALL 23 pairs copies itself so now there is 46 pairs of chromosomes (23 for each new cell).
prophase- The DNA in the chromosomes are more visible now, and the membrane around the nucleus disappears ready for the next stage
metaphase- Chromosomes and their copies line up in the middle of the cell, so that they could be pulled apart in the next stage
anaphase- Spindle fibres attach themselves to either end of the chromosome. They are then pulled apart to either ends of the cell. 23 on one side, 23 on another.
telophase- membranes form around the 23 pairs of chromosomes at their end of the cell. Two new daughter cells are produced. The cell membrane pinches in and divides the cells in two.

Answers
Answer:
Explanation:
Weight on a human body is mainly stored as muscle or fat. When we exercise we don't necessarily lose fat. Instead, the fat cells tend to shrink in size but remain the same amount. Fat is converted into energy which the body uses to function. This energy is expelled from the body in many different forms such as carbon dioxide and sweating. Therefore those are the matter that the individual in question lost when losing the 215lbs

How do you think the organisms interact with each other?
Answers
Answer:
There are four main types of species interactions that occur between organisms in an ecosystem: Predation, parasitism and herbivory - In these interactions, one organism benefits while the other is negatively affected. * Competition - Both organisms are negatively affected in some way due to their interactions. Individual organisms live together in an ecosystem and depend on one another. Some organisms can make their own food, and other organisms have to get their food by eating other organisms. An organism that must obtain their nutrients by eating (consuming) other organisms is called a consumer, or a heterotroph.

What does a Euglena require to exhibit phototactic behavior?
A.
a contractile vacuole
B.
cilia
C.
an eyespot
D.
a pseudopod
Answers
Answer:
C
Explanation:
Phototaxis (phototactic response) is the cellular behavior in which cells swim toward or away from the light source. The euglena have eyespots that detect light so that it can move toward sunlight for photosynthesis.
Euglena require an eyespot to exhibit phototactic behavior. Thus option C is correct.
what is phototaxis ?Phototaxis is defined as the movement of an organism in response to external stimulus that means light, it is a locomotory movement of living organisms towards the source of light or away from the source of light.
Taxis means the movement of an organism in response to a stimulus like light or food, it is an innate response of an organism to variation in light intensity and direction.
More is the intensity of light in a particular direction the more will be phototactic stimulation occurs in the organism, its own biological reason and phototactic response are incidental and serve no end purpose.
The advantages of phototaxis are the regulation photosynthesis, the finding of food in phototrophic organisms, facilitation of larval dispersal, or the increased likelihood of gamete fusion on the surface.
Thus option C is correct.
