Answer:2
Explanation:
Frequency is defined as repetitive occurrences per unit of time. The frequency of a 6.43 x 10⁻⁵ m wave is 4.67 × 10 ¹³ hertz.
What is the frequency?Frequency is given as the ratio of the wave speed (c) to the wavelength (λ).
υ = c ÷ λ
Given,
Speed of light (c) = 3.00 x 10⁸ m/s
Wavelength (λ) = 6.43 x 10⁻⁵ m
Substituting the values above,
υ = 3.00 x 10⁸m/s ÷ 6.43 x 10⁻⁵ m
= 4.67 × 10 ¹³ per sec
Therefore, 4.67 × 10 ¹³ Hz is the frequency.

what is the relationship between the rate of wind and the amount of abrasion?
Answer: Wind speed is also important. The rate of erosion caused by a 30-mile-per-hour wind is more than three times that of a 20-mile-per-hour wind. Wind erosion decreases as soil moisture increases. For example, dry soil erodes about one-and-one-third times more than soil with barely enough moisture to keep plants alive.

Match each idea about evolution to the person or group where it originated from the drop down menu
Hello. You did not present the ideas about evolution to which the question refers, which makes it impossible for your question to be answered. However, I will try to help you in the best possible way, showing you the main ideas about evolution and the people who originated them.
According to Jean-Baptiste organisms evolve as a way of seeking perfection.
According to the ancient Greeks and Romans, all living things are in a constant process of change. This change causes evolution and when a living being evolves it causes the evolution of another living being, since everyone is connected and related.
According to Darwin, evolution occurs over time and through an ancestor. For him All living beings have a common ancestor, which evolved over time and generated new species. Darvin also believes that any characteristic acquired by evolution could be passed on to the descendants.
According to Malthus, living beings generate a number of descendants disproportionate to the resources necessary for their survival and this causes evolution.
The structure labeled X enables this plant cell toa.Release energyb.Store waterc.Control nuclear divisiond.Manufacture proteins
About the question:
You will find the cell image in the attached files
Answer:
b.Store water
Explanation:
Here we are looking at a vegetable cell. And specifically, the X letter is labeling a vacuole, which we can recognize by its size.
We can find vacuoles either in animal or vegetable cells. They are essential to the correct functioning of the cell.
Now we are going to describe a vegetable cell vacuole.
Usually, they occupy a central place on the vegetable cells. They are big organules, representing almost 90% of the total cell volume. They are the biggest-sized organelle of vegetable cells.
Vacuole formation is thanks to the fusion of many vesicles release by the Golgi complex, and sometimes, with the RER intervention. There are different types of vacuoles according to their function, and many times, a single cell might carry different types of vacuoles. These organelles harbor diverse fluids, among which there are water and enzymes. Eventually, they can also contain solid substances such as proteins, salts, and sugars.
Vacuoles accomplish different functions. The main one is to keep turgor, store waste elements, and substance degradation. Here we are going to focus on the turgor function that involves water storage.
Turgor is a measure of hydrostatic pressure against the cell walls and controlled by these organelles. Vacuoles incorporate substances in their interior such as ions, creating an osmotic environment variable concerning the cytoplasmic one. This environmental variability produces a water flow from inside to outside and vice-versa. The capability of water storage is crucial for vegetable cells.
15. Cells found in plants and animals have similarities but can differ in function. Consider the following two organisms: a corn plant cell (Zea mays) and a camel cell (Bactrianus ferus). What is the best explanation for the difference in the cellular vacuole size between these two biotic organisms?
A. The corn cells' have a small vacuole size because it does not need long term water and
electrolyte storage.
B. The camel cells' have a small vacuole size because it does not need long term water and electrolyte storage.
C. The camel cells' have a small vacuole size because it is not in contact with toxins that need to be removed from the cell.
D. The corn cells' have a large vacuole size because it is in contact with many toxins in the soil which need to be removed from the cell.
The best explanation for the difference in the cellular vacuole size is option d. The corn cells' have a large vacuole size.
Explanation to the difference in the cellular vacuole size:When there is the difference in the vacuole size that lies between the two biotic organism so it is due to the corn cells that contain high vacuole since they are in contact with various toxins in the soil that need to be eliminated from the cell.
hence, the correct option is d.
And, the rest of the options are wrong.

Which components bond with andenine in a section if double stranded DNA
Answer: 3 and 5 only
Explanation:
Adenine is a purine nitrogenous base and it pairs with thymine which is a pyrimidine nitrogenous base with a triple hydrogen bond in a DNA structure. The adenine binds with thymine directly and indirectly with a deoxyribose sugar which is attached with it in the back it forms the part of sugar phosphate backbone and in the front hydrogen bonding helps in the stabilizing the DNA structure by binding two separate strands of DNA in a stable double helical structure.

Electrophysiological cell-recording studies have indicated that the _______ may be especially important in the control of internally guided motor sequences, whereas the _______ may be especially important in the control of externally guided motor sequences. A. supplementary motor cortex; premotor cortex B. premotor cortex; supplementary motor cortex C. cerebellum; basal ganglia D. basal ganglia; cerebellum
Answer:
A. supplementary motor cortex; premotor cortex
Explanation:
The supplementary motor cortex, also known as the supplementary motor area (SMA), is an area of the cerebral cortex located anterior to the premotor cortex. This area (SMA) is involved in the execution of complex and rapid sequential movements (e.g., typing). Moreover, the premotor cortex is an area of the motor cortex located between the primary motor cortex and the prefrontal cortex. This area (premotor cortex) is activated during motor tasks including, among others, spatial and sensory guidance of movement.

 True or False: If two organisms are located near one another on a phylogenetic tree they share a recent common ancestor.
HELP ILL MARK BRAINLIEST!
Answer:
True
Explanation:
When are the two organisms that share the most common ancestor in the tree 1. the sequence of branching does not necessarily indicate the actual (absolute) ages of the particular species 2. we cannot assume that a taxon on a phylogenetic tree evolved from the taxon next to it (just bc two species are located near each other does not mean the are more clostly related)
“Phylogenetic relationship” refers to the relative times in the past that species shared common ancestors. Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).
