The track star runs 100m at a rate of 10.4m/s. How long did it take to run 100m?
Answer:
Time, t = 9.62 secs.
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex] ....equation 1
Making time the subject formula;
[tex]Time = \frac{distance}{speed}[/tex] .....equation 2
Given the following data;
Distance = 100m
Speed = 10.4m/s
Substituting into equation 2;
[tex]Time = \frac{100}{10.4}[/tex]
Time, t = 9.62 secs.
Identify the plant tissues in the three images.
A
B.
C
I originally asked for the images but I will give it my best shot at answering your question without them! :D
There are only three types of plant tissues:
1. Dermal
2. Ground
3. Vascular
The dermal tissue is the outside of the plant's root, stem, or leaf, A.K.A the the skin. If you're looking at a circular image, what ever is pointing to the outside ring of the stem is the dermal tissue.
The ground tissue is the flesh of the plant that is inside the dermal tissue. It surrounds the vascular tissue in the middle of the stem. Whatever letter is pointing to the wide, fleshy ring, that is touching the dermal tissue is the ground tissue. It is the largest part of a plants stem, roots, or leaves.
Lastly, the very inner ring or rings of the plant is the vascular tissue. It's made up of xylem and phloem. This can be found in many different places depending on the part of the plant, but what you're looking for is tiny circles within the ground tissue. If you're looking at the roots, you will see one circle in the very center of the plant, surrounded by ground tissue. If you're looking at the leaves, you will see one circle as well, and additionally other tiny circles throughout the ground tissue in each wing. Lastly, if you're looking at the stem, you'll see a circle of tiny circles within the ground tissue. These small circles are all vascular tissue.

The dermal tissue is the outermost layer of cells that covers the plant. It is responsible for protecting the plant from the environment. The vascular tissue is a system of tubes that transports water and nutrients throughout the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.
In the image, the dermal tissue is the thin layer of cells that covers the surface of the leaf. The vascular tissue is the network of tubes that runs through the leaf. The ground tissue is the bulk of the leaf, and it is made up of cells that contain chloroplasts.

The xylem is a type of vascular tissue that transports water and nutrients from the roots to the rest of the plant. The phloem is another type of vascular tissue that transports sugars from the leaves to the rest of the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.
In the image, the xylem is the dark brown tissue that runs through the center of the stem. The phloem is the lighter colored tissue that surrounds the xylem. The ground tissue is the bulk of the stem, and it is made up of cells that contain chloroplasts.

what does a endoplasmic reticulum do?
Answer: nothing
Explanation:
Answer: produce proteins for the rest of the cell to function
Explanation:
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Multicellular fungi share some key traits, including their body structures, growth patterns, and methods for absorbing nutrients. however, although their feeding methods may be similar, fungal species differ markedly in their sources of nutrients, which include both living and dead organisms. as a result, fungi play a variety of roles in ecological communities.
Explanation:
The structure of multicellular fungi is formed by filaments called hyphae, and the set of hyphae is called mycelium. Hyphae are made up of the substance chitin.
They can be of two types: vegetative or reproductive. In vegetative multicellular fungi, hyphae are found inside the substrate to remove the food.
And in the case of reproductive multicellular fungi, there is the formation of spores, which will form the fruiting body for reproduction.

Owls (primary predators of rock pocket mice) are nocturnal visual predators that are able to distinguish effectively between dark and light colors in low-light conditions,
Which of the following best explains the relationship between coat color and predation rate in the rock pocket mouse population on the lava flow rocks with
respect to the different coat color
phenotypes?
Answer: A dark coat color provides camouflage to mice on the lava flow rocks; therefore, mice with dark coats have a lower predation rate in that habitat.

In 1907, Dr. Duncan MacDougall performed a series of experiments in which he attempted to measure the weight of the soul as it left a dying person. In his experiments, MacDougall placed a dying person on a scale and measured their weight immediately prior to and following death. MacDougall determined the change in weight to be approximately 21 grams. From these experiments, he concluded that the soul exists and has mass. What is the fundamental scientific flaw in his conclusions? (5 points)
They are based on the concept of the soul, which is beyond the bounds of science.
They are based on the idea that the soul is made of matter, not energy.

what happens to the 90% of energy available if 10% moves on to the next trophic level
Answer:
Released as heat
Explanation:
The vast majority of energy in the ecosystem is used by the organisms to power chemical reactions in the cell.
Therefore, this energy is lost as heat when it powers metabolic processes, rather than being passed on to the next trophic level.

summarize the importance of stem cells
Answer:
Stem cells can become almost any cell in the human body.
Explanation:
This is important because in embryonic development, the body uses stem cells to form each individual part. For example, a single stem cell could become a heart cell, or brain cell, or a blood cell, or more. This is also important for possible treatments. In order to heal damaged or diseased bone tissue, blood stem cells can be taken out of the same person and used to fix the tissue. This allows for a lower rejection rate sense the cells used to fix the tissue were already part of the person's body.

9. The phases of the moon are the regular changes in how the moon looks from Earth. In which phase is the moon completely visible from Earth?
Group of answer choices
A. Full moon
B. New moon
C. Waxing gibbous
D. Waning crescent
Answer:
A, full moon
hope this helps ;)
In the full moon phase, the moon is completely visible from the Earth. Therefore, the correct option is A.
What are the phases of the moon?The phases of the moon results from the changing position of the moon relative to the Sun and the Earth.
There are 8 phases of the moon:
1.) New moon-The moon is between the sun and the earth, with its illuminated side facing away from us.
2.) Waxing crescent-The moon is partially illuminated increasing in size, appearing as a crescent shape.
3.) First quarter-The moon is 90 degree east of the sun and appears as a half moon shape.
4.) Waxing Gibbous-The moon appears as gibbous shape.
5.) Full moon-The moon is on the opposite side of the earth from the sun, and its entire illuminated side is visible.
6.) Waning gibbous-The moon is partially illuminated and decreasing, appearing as a gibbous shape.
7.) Third quarter-The moon is 90 degree west of the sun and appears as a half moon shape.
8.) Waning crescent-The moon is partially illuminated and decreasing, appearing as a crescent shape.
The cycle of phases repeats approximately every 29.5 days, from new moon to new moon. Therefore, the correct option is A.
