Answer:

Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.

a. True

Explanation:

A woman's estrogen levels become highest towards the end of her ovulation.  At this point, the woman is naturally prepared for a possible pregnancy.  The occurrence of the highest estrogen levels coincides with the luteal phase, a stage of a woman's menstrual cycle, which occurs after ovulation (or the release of eggs from the ovaries), and before the start of the normal period. This luteal phase has been observed to be within 14 days for all women.  By the end of the luteal phase, the corpus luteum function declines.

The primary reason organisms undergo cellular respiration is to convert food to usable energy.

Cellular respiration is a metabolic process that occurs in the cells of living organisms and involves the breakdown of organic molecules, such as glucose, to release energy in the form of ATP. This process is essential for cells to carry out their normal functions and for organisms to maintain their life processes.

Cellular respiration involves a series of reactions that break down glucose into smaller molecules, which are then used to generate ATP. During this process, oxygen is consumed and carbon dioxide is produced as a waste product. The process of cellular respiration is an efficient way for cells to convert the energy stored in food molecules into usable energy, which is essential for cell growth, repair, and reproduction.

In contrast, photosynthesis is the process by which plants and some bacteria use energy from sunlight to convert carbon dioxide and water into glucose and oxygen. This process is essential for plants to produce their own food and to release oxygen into the atmosphere.

Explanation:

One resource used for energy production that can impact the natural resource of ozone layer depletion is coal. Burning coal releases pollutants like sulfur dioxide, nitrogen oxides, and mercury into the atmosphere, which can contribute to the formation of smog and acid rain. These pollutants can also react with other chemicals in the atmosphere to break down ozone molecules, contributing to the depletion of the ozone layer. So, the way humans use coal as an energy resource can have a negative impact on the ozone layer and the environment.

Answer:

Based on the first study it is evident that the ecologists are looking for functional diversity as they are making a note of different functions performed by a distinct kind of species found on different plots.  

On the other hand, based on the second study it is evident that the ecologists are studying the species diversity as with the assistance of different wavelengths of light reflected by the vegetation, they are differentiating between the vegetation found in different parts of the continent.  

The biodiversity helps humans in different ways, that is, by supporting the society in which they live and by maintaining a healthy biosphere. The biodiversity found around helps in the procedure of dead species decomposition, they offer humans with nutritious food, and also acts as natural sieves and clean the water for consumption. Hence, the correct options are 1, 2, and 3.  

Answer:

"Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process."

This question is incomplete; the options are:

A. It was an atom.

B. It was a mixture.

C. It was an element.

D. It was a compound.

The answer is B. It was a mixture.

Explanation:

A mixture is a substance which contains two or more different substances (with differing properties) that can be easily separated from each other. Each component of a mixture retains their individual properties, hence, they can be separated via physical means.

According to this question, a scientist is conducting an investigation where it was observed that the solid involved has two melting points. After heating the solid, the scientist is able to separate the two resulting liquids. This suggests that the original solid substance was a MIXTURE because it could be separate using heat.

Explanation:

There was a change in the  view on smoking after 1960. change was influenced by declaring tobacco as an addiction and that it can cause cancer. It started in the 1964.

Answer:

Explanation:

The major cause of the change that society had on its view on smoking since 1960 was because of scientific information wherein scientists found that smoking causes cancer.

Ever since scientists discovered that smoking is bad for the lungs and the body in general, over time there became fewer and less people who do it. The smoke of cigarettes contains around 70 chemicals called carcinogens. These are known to cause cancer. So, society has changed its view on smoking since 1960.

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.  Have a blessed day!! :D

Force caused the change in the fireballs velocity as it travelled.

A force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull.

A force is a vector quantity which means that it has both a magnitude (size) and a direction associated with it. If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium.

The SI derived unit used to measure energy or work. One joule is equal to the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter.

The correct options for the given question are given below:

a. use water that is cold

b.boil the water before use

c. take the water in a clear cup

d. measure the exact amount of water used

Answer:

The correct answer is - C. take the water in a clear cup.

Explanation:

In order to check that if light can pass through the water to which a few drops of black ink have been added Rajan needs to have water in a clear cup or container and put some drops of black ink added to it and place the cup in the light.

There must be a clear cup so it can be observed if the light passes through the ink and reach below the surface covered with the ink as ink spread over the water surface due to surface tension of the water and difference in the density. So to check the light passes or not it requires a clear or transparent cup.

For the word problem, If the difference of a number and the fraction \(\frac{4}{3}\) is \(\frac{11}{3}\), then the number is 5.

The above mathematical problem is a word problem. Word problems are problems that are written in words, rather than in symbols.

To solve for the difference or mystery number, we say, Let x be the number.

The problem states that x -  \(\frac{4}{3}\) =  \(\frac{11}{3}\),

movin -  \(\frac{4}{3}\) to the other side of the equation,

we get x = \(\frac{11}{3}\) + \(\frac{4}{3}\) = \(\frac{15}{3}\)

We solve the fraction by dividing 15 by 3

\(\frac{15}{3}\) = 5

Homo erectus overlapped in time with Australopithecus. Homo erectus had large browridges.

Early hominins belonging to the genus Australopithecus lived in Africa in the Late Pliocene and Early Pleistocene. The name comes from the Latin australis, which means "southern," and Ancient Greek. Modern humans are members of the genus Homo, which developed from Australopithecus as a sister group to species like Australopithecus sediba. Within Australopithecus, the taxa Paranthropus and Kenyanthropus also appeared. Although the name "australopithecine" is occasionally used to refer exclusively to individuals of Australopithecus, Australopithecus is a member of the subtribe Australopithecina. Afarensis, Anamensis, A. bahrelghazali, A. sediba, A. garhi, A. africanus, B. bahrelghazali, and A. deyiremeda are among the species. Because of the taxonomic discrepancy, there is debate about whether some Australopithecus species should be placed in new genera or whether Paranthropus and Kenyanthropus are the same species as Australopithecus.
