Plants that we reconize today spend the majority of their life in the “blank”

A) haploid Phase

B) seed phase

C) diploid phase

D) gametophyte

Answers

Answer:

The answer is C diploid Phase

Answer:

The answer is C.

Explanation:

Plants that we reconize today spend the majority of their life in the diploid phase.

During the sporophyte phase, a diploid plant body (one with two sets of chromosomes) develops and finally generates spores via the process of meiosis. Mitotic division of these spores results in the formation of gametophytes, which are gamete-producing organisms that are haploid (have a single pair of chromosomes).

Answer:

6. As the lunar cycle progresses from the full moon to new moon the light will appear to decrease

7. The “growing light” that appears during the first half of the lunar cycle is referred to as waxing.

8. The third quarter / 7th phase occurs at 21 days into the cycle and shows the left half of the moon illuminated.

9. In a crescent stage less than half of the Moon appears illuminated and during a gibbous stage more than half appears illuminated.

Explanation:

The "growing light" that appears during the first half of the lunar cycle is referred to as the "waxing phase" ,the first quarter phase occurs 21 days into the cycle and in the crescent stage, less than half of the moon appears illuminated.

What is the significance of the lunar cycle?

It has much significance and is related to the moon, which is a natural navigation aid for mariners, providing light at night and it has an impact on the life cycles of animals and plants, including breeding and migration, and the gravitational pull of the moon and the sun causes the tides to rise and fall.

Hence, the "growing light" that appears during the first half of the lunar cycle is referred to as the "waxing phase" ,the first quarter phase occurs 21 days into the cycle and in the crescent stage, less than half of the moon appears illuminated.

The microscopic filtering units found in the kidneys that are responsible for urine formation are called

Answers

Answer:

nephrons

Explanation:

there are about one million nephrons in one kidney which are responsible for urine formation

The microscopic filtering units found in the kidneys that are responsible for urine formation are called nephrons, so here the correct option is option a.

Throughout the nephron, various processes such as filtration, reabsorption, and secretion occur to produce urine. Filtration occurs at the glomerulus, where water and small solutes are forced out of the blood into the Bowman's capsule. Reabsorption involves the selective reabsorption of water, ions, and nutrients from the filtrate back into the bloodstream. Secretion involves the active transport of waste products, excess ions, and toxins from the bloodstream into the filtrate. So here, the correct option is option a.

A scientist performs a series of mutation screens to look for mutations that reduce ATP production. One of the mutants, compared to a wild-type cell, has reduced levels of ATP and NADH and increased levels of FAD and pyruvate. Which hypothesis best fits these observations?

Answers

The hypothesis that best fits the observation that one of the mutants has reduced levels of ATP and NADH and increased levels of FAD and pyruvate is that the mutation is disrupting the citric acid cycle (Option 3).

What is the citric acid cycle?

The citric acid cycle, also known as the Krebs cycle, is the second step of cellular respiration which is required to generate ATP through the oxidation of pyruvate.

The reduced form of Nicotinamide adenine dinucleotide (NADH) produced during the citric acid cycle is then used in oxidative phosphorylation (the third step of cellular respiration) in order to generate more ATP.

Therefore, with this data, we can see that the citric acid cycle generates the reduced form of Nicotinamide adenine dinucleotide (NADH) and thus increases the production of ATP, thereby a mutation in an enzyme that works in this pathway may also hamper the proportion of ATP.

Compare 41 Calories to 410 kcal (1 kcal = 1,000 calories). (1 point)
O 41 Calories is greater than 410 kcal
O 41 Calories is equal to 410 kcal
41 Calories is less than 410 kcal
It is not possible to compare these two values

Answers

From the calculation, we can deduce that 41 Calories is less than 410 kcal.

Given the following data:

Energy in calories = 41 CaloriesEnergy in kcal = 410 kcal

To compare 41 Calories to 410 kcal, we would simply convert the given values to the same base values:

Hence, we would make Calories the base value by converting the value in kcal to Calories as follows:

Conversion:

1000 Calories = 1 kcal

41 Calories = X kcal

Cross-multiplying, we have:

[tex]1000X =41\\\\X=\frac{41}{1000}[/tex]

X = 0.041 kcal.

The non-cognitive disturbances that Mrs. W. could have related to some dementia are psychosis, personality change, lack of rhythm, deficit in emotional responses, mental confusion.

It is important that the patient in these conditions is continuously assisted, to avoid situations that put her safety at risk.

An elderly woman like Mrs. W, who already has significant evolution of non-cognitive disorders, must have an effective medical apparatus and a tutor willing to help with care and daily activities.

Ideally, caregivers should develop optimal communication skills for patients with these disorders, such as a calm and gentle tone, provide the individual with a peaceful environment without too much noise or other disturbances, as well as being considerate and not neglecting the individual's needs.
