Describe Lamarck’s idea about how organisms evolved. Use the giraffe’s neck as an example.
Answer
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
Lamarck believed that the stretching elongated the giraffe's neck, which became a useful characteristic and was passed onto future generations. This resulted in the length of the giraffe's neck increasing over time. It is now commonly accepted that Lamarck's ideas were wrong.

Explanation:
Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.
Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.

Answer:
It changes the amount of friction there is. There is more friction where water is shallow, and less friction where water is not as shallow. The friction has the power to cause erosion as it causes movement of water.
why can AIDS be classified as both an infectious disease and an immune system disorder ?
Answer:
Because AIDS can not only be passed from person to person but it can also affect your immune system in ways other infections diseases can not.
Explanation:
for example: type 1 diabetes is an auto-immune disorder and can not be passed on by bodily fluids. chlamydia is an infectious disease that can be passed on by bodily fluids.
AIDS is an auto immune disorder because it affects the immune system in the same ways that other auto-immune disorders do. this being so it can all so be found in the blood and passed on like an infection where as auto-immune disorders normally dont live in a persons blood.

Jordan's grandmother uses the juice from squeezed lemons to remove stains from his shirt. He hypothesizes that the juice is the only part of the lemon that is effective at removing the stains, because it’s an acid. Which two steps would help Jordan determine whether his hypothesis is scientifically supported?
Answer: I would say The hypothesis that the juice of the lemon is the only pat of lemon that is capable of removing stains from the t-shirt is because the lemon juice is acidic in nature.
1.) To test the validity of this hypothesis he should test the acidity of different parts of the lemon including the juice, pulp and skin of lemon.
2.) He should also compare the lemon juice with other juices to know weather other juices are also helpful in removing stains from the t-shirt.

FROM THE LUNGS, BLOOD COMES BACK TO THE HEART. DESCRIBE THE PATH THIS BLOOD FOLLOWS UNTIL IT ENTERS THE AORTA.
Answer:
Tricuspid valve is the path of blood through the heart and lungs
Explanation:
Blood is also responsible for transiting the blood and nutrients. The blood reached right atrium and from here it reached the right ventricles with the help of tricuspid valve. When the ventricles are full it closes to stop blood from going back to the atrium.
The inferior and the superior vena cava let the blood enter through them. The heart left the blood with the help of pulmonary valve to the pulmonary artery and the blood reached the lungs.

Describe the difference between one's gender identity and one's sexual identity.
Answer:
Gender identity is your own, internal, personal sense of being a man or a woman (or as someone outside of that gender binary).
Sexual orientation describes a person's enduring physical, romantic, and/or emotional attraction to another person (for example: straight, gay, lesbian, bisexual).
Explanation:
Gender identity is your own, internal, personal sense of being a man or a woman whereas sexual orientation describes a person's enduring physical, romantic, and/or emotional attraction to another person.
What do you mean by gender identity?Gender identity is the personal sense of one's own gender. Gender identity can correlate with a person's assigned sex or can differ from it. In most individuals, the various biological determinants of sex are congruent, and consistent with the individual's gender identity.
Gender identity is each person's internal and individual experience of gender. It is a person's sense of being a woman, a man, both, neither, or anywhere along the gender spectrum. A person's gender identity may be the same as or different from their birth-assigned sex.

Why do two grams of fat provide a different amount of energy than two grams of carbohydrates? (2-3 sentences)
Answer:
Fats are the slowest source of energy but the most energy-efficient form of food. Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates. Because fats are such an efficient form of energy, the body stores any excess energy as fat.

Considering only the values of 0 for which the expression is defined, which of the following is equivalent to the expression
below?
sin0 x tan0 x sec0 x cot(-0)
Select the correct answer below:
O-tan
O cot0csc0sec0
O-cot0csc0sec0
O tan0
Answer:
A. [tex]-tan\theta[/tex]
Explanation:
Given
[tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta)[/tex]
Required
Simplify
[tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta)[/tex]
Substitute [tex]\frac{1}{cos\theta|}[/tex] for [tex]sec\theta[/tex]
So, the expression becomes
[tex]sin\theta\ .\ tan\theta\ .\ \frac{1}{cos\theta} .\ cot(-\theta)[/tex]
Rearrange the above expression
[tex]sin\theta\ .\ \frac{1}{cos\theta}\. \ tan\theta\ .\ cot(-\theta)[/tex]
[tex]\frac{sin\theta}{cos\theta}\. \ tan\theta\ .\ cot(-\theta)[/tex]
From trigonometry;
[tex]tan\theta = \frac{sin\theta}{cos\theta}[/tex]
So, we have
[tex]tan\theta\ . \ tan\theta\ .\ cot(-\theta)[/tex]
From trigonometry;
[tex]cot(-\theta) = -cot(\theta)[/tex]
So, the above expression becomes
[tex]tan\theta\ . \ tan\theta\ .\ -cot(\theta)[/tex]
[tex]-tan\theta\ . \ tan\theta\ .\ cot(\theta)[/tex]
From trigonometry;
[tex]cot\theta = \frac{1}{tan\theta}[/tex]
So, we have
[tex]-tan\theta\ . \ tan\theta\ .\ \frac{1}{tan\theta}[/tex]
Express as a single fraction
[tex]\frac{-tan\theta\ . \ tan\theta }{tan\theta}[/tex]
[tex]-tan\theta[/tex]
Hence, [tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta) = -tan\theta[/tex]
