How does the process of ridge push cause the formation of new oceans?
Answer:
Explanation and answer below
Explanation:
Ridge push causes a rift valley; as the plates move apart, a new ocean basin forms, filling with water and eventually becoming a mature ocean. Ridge push causes a convergent plate boundary; as the plates move together, new islands form, which “trap” water between them, causing an ocean to form.

Why xylem and phloem are called complex tissues? How are they different from one another?
Answer:
Xylem and phloem are called complex tissues because they are made up of more than one type of cell working together as a unit. The xylem transports H2O and minerals upward from the roots to the leaves, and is composed of tracheid cells which are dead at maturity (no active nucleus, makes the tree stem hard). If plants don't have xylem, they will stay lower to the ground as it is responsible for making the tree grow upward. The ends of the xylem tubes are tapered (pointed), materials are passed along one cell at a time, and the tubes are narrow and continuous. The phloem transports sugars and proteins downward from the leaves to the stems and storage roots. The cells that make up the phloem are called sieve tubules and companion cells. The companion cells have the nucleus and the sieve tubules contain the cytoplasm.
Explanation:
My teacher helped us remember using the phrase "phloem down the river" because it sounds like 'flowing down the river' (to help remember that phloem transports downward and xylem transports upward.)

Answer
Pacific Plate, oceanic tectonic plate
Explanation:
the large brown plate is pacific plate was under the ocean and also named after the ocean pacific ocean. so it is easy to guess
hope you understood it . it was my explanation up for more info down i have pasted what they told in google.
Pacific plate
In fact, six of the seven major tectonic plates are named after the continents they contain. The one exception is the Pacific plate, which lies beneath the Pacific Ocean. Not only is this the only major tectonic plate that is mainly underwater, it is also the largest, spanning over 100 million square kilometers.
Pacific Plate. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate. The Pacific Plate contains an interior hot spot forming the Hawaiian Islands.
State three things you do each day that affect the environment around you. Explain how the things you do affect the environment around you.
Answer:
Driving or using cars as a method of transportation increases the amount of Co2 released into the atmosphere. Due to this the environment becomes less and less unstable. Another daily thing I do every day that effects the environment is throwing away trash. As our trash fills the landfills some of them can be picked up by birds or even end up getting blown into the ocean. However, recycling is one positive aspect in our every day lives. When we recycle companies and factories are able to reuse things we no longer use. Because of this we are able to protect many ecosystems and the environment.

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]

Which explains why the reflex reaction is important in certain situations?
O A. Motor neurons cannot form action potentials.
O B. The brain has no control over motor neurons.
O C. Interneurons are too slow at sending signals through the spinal
cord.
O D. Sensory neurons do not use neurotransmitters to send signals.
Answer:
Answer:c
Explanation:
The reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.
What is the reflex?The reflex is an automatic (read immediate and constant) bodily reaction to stimulation. According to Pieron, the reflex corresponds to any activity or variation of activity of an effector (muscle, gland, etc.)
With this information, we can conclude that the reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.

how do animals survive in both water conditions
Answer:
they have adapted to the temperatur since water trafers water faster than air. (more info below)
Explanation:
animals also have adaptations to temperature control, as water transfers heat faster than air. At the end of the day, aquatic animals have a lot of adaptations for moving in the water, such as a streamlined design, flippers, and a swim bladder, which acts like a fish ballast.

Humans and gorillas have one different amino acid in their hemoglobin
sequence. What does this say about the evolution of these two species?
A. Gorillas recently evolved from humans.
B. They have no common ancestors.
C. They probably have
recent common ancestor.
O D. They are probably the same species.
SUBMIT
Answer:
they probably have a recent common ancestor
Explanation:
They probably have recent common ancestor. Therefore, option (C) is correct.
What is evolution?Evolution is the process by which species change over time, usually through natural selection. The theory of evolution is supported by a vast body of evidence from many fields, including genetics, paleontology, and comparative anatomy.
Evolution occurs because of changes in the genetic code of organisms, which can be caused by mutations, gene flow, genetic drift, and natural selection. Over time, these changes can accumulate and result in the development of new species from ancestral forms. Evolution is a slow process that occurs over many generations, and it has been responsible for the incredible diversity of life on Earth, from the simplest bacteria to the most complex animals and plants.
The fact that humans and gorillas have one different amino acid in their hemoglobin sequence suggests that they have a recent common ancestor. This is because the hemoglobin protein plays an essential role in carrying oxygen in the blood and is highly conserved across species that share a common ancestor.
