Explanation:
what keeps tectonic plates from moving??
Answer:
The Upper Mantle keeps it from moving
Answer:For tectonic plates to stop moving, the Earth’s mantle will have to be too cold for convection to occur.
Explanation: If that were to happen, then it means the Earth’s outer core has likely solidified. Normally a liquid layer, the outer core, transfers heat between the inner core and the mantle.

Which is a use for peat moss?
A. purifying water
B. putting out fires
C. providing fuel
D. curing blurred vision
Answer:
d
Explanation:
Peat moss is used for purifying water. So, the correct option is (A).
What is Peat moss?Peat moss is defined as the dark brown fibrous product of sphagnum moss and other organic materials that decompose in peat bogs over thousands of years.
Peat is described as a product created from organic matter that sinks into bogs which can be made of various materials, but a large percentage of harvested peat is made up of sphagnum moss, hence the name peat moss.
Almost any potted plant we can buy in a soil mix contains peat moss, and so do most bagged potting soils where we can even buy it to mix into our potting soil mix.
Thus, Peat moss is used for purifying water. So, the correct option is (A).

How has the poison changed the concentration of pyruvate, NADH and intermembrane H in Jared's cells?
Answer:
pyruvate - stays the same
NADH increase
intermembrane H+ - decrease
Explanation:
Pyruvate - stays the same, NADH increase and intermembrane H+ - decrease.
What is NADH?Nicotinamide adenine dinucleotide (NAD) plus hydrogen (H) is referred to as NADH. It occurs naturally in the body and contributes to energy production.
The body generates NADH, which is used to produce energy. Supplementing with NADH may have negative effects on the body, including the blood pressure.
People use NADH for a variety of ailments, including Parkinson's disease, depression, high blood pressure, high cholesterol, sports performance, and chronic fatigue syndrome (CFS), but there isn't any solid scientific evidence to back these claims.
Therefore, Pyruvate - stays the same, NADH increase and intermembrane H+ - decrease.

Explanation:
The elements in the "Periodic Table" are arranged in groups according to their characteristics.
X- Selenium
Z- Xenon
W- Magnesium
Y- Barium
A. X has a lower boiling point than Y. Selenium's boiling point is 685 while Barium's boiling point is 1,140. This makes choice A incorrect.
B. Y is a metal while Z is a non-metal. This makes choice B incorrect.
C. Both W and X are non-metals. Both are in the Alkaline Earth group. This makes choice C correct.
D. Z has different chemical properties than W because they don't belong in the same group. Z is a noble gas while W is an Alkaline Earth Metal.

What specialized structures in flowering plants increase the probability of
successful reproduction?
Answer:
There a few structures that can increase the chances of successful reproduction; 1) Brightly colored flowers that attract butterflies, bees, and hummingbirds which are pollinators, 2) Fragrant odors emitted from said flowers, and 3) Nectar that is consumed by pollinators.
The flowers are a source of food and nectar on which the bees feed on these bees tend to pollinate and help in the germination of new flowers as they are agents of pollination
Except that winds are also responsible for the successful reproduction. The factors that determines the successful reproduction is based on the color of the flowers. Such as more bight and vibrant flowers favors more reproduction. These flowers attract insects, butterflies, and birds.Hence the bright flowers are the answer.

Did the hospital make a mistake?
Yes, because the physical appearance of
the baby must have tall eyeballs.
No genotypes of the punnet square include a homo-zygous recessive trait.
Therefore the offspring must recieve a recessive allele from each parent to exhibit it so based on the data, it is impossible to have a baby with short eyes.
32. Which of the following does NOT cause eutrophication?
a. Runoff of oil from roads
c. Runoff of manure from farms
b. Runoff of fertilizers from neighborhoods
d. Excessive nutrients
Answer:
a
Explanation:
d coukd be included but im not sure if it means excessive nutrients in the water or farm
RUNOFF OF OIL FROM ROADS
Eutrophication is a phenomenon used to describe an INCREASE in the concentration of nutrients in a particular aquatic area (lake) leading to the proliferation of plant or algae growth. Proliferation is majorly caused by the RUNOFF of substances containing these nutrients into a water body.
According to this question, eutrophication can be caused by the following:
- Runoff of manure from farms: Manure contains nutrients that can cause an increase plant/algae growth.
- Runoff of fertilizers from neighborhood: Fertilizer contains certain elements such as nitrogen, phosphorus, potassium etc. that serves as source of nutrients for aquatic organisms.
- Excessive nutrients: Too much of nutrients lead to uncontrollable growth.
Among these options, runoff of oil from road is NOT a cause of eutrophication because OIL inhibits growth rather than induce it.

Which is a description of the Paleozoic era?
A. The rise of life
B. The age of the dinosaurs
C. The hottest era
D. The era of humans
Answer:
The rise of life
Explanation:
A.P.E.X.
A description of the Paleozoic era is A. The rise of life.
What is the Paleozoic era?The Paleozoic Era was a geological era that spanned from about 541 to 252 million years ago. It is often referred to as the "Age of Invertebrates" because it was during this time that the first major diversification of animal life occurred, and most of the animal life was invertebrates.
This era also saw the emergence of fish, amphibians, reptiles, and the first land plants. The Paleozoic Era ended with the largest mass extinction in Earth's history, known as the Permian-Triassic extinction event, which wiped out about 96% of marine species and 70% of terrestrial species.
The Paleozoic Era is a geologic era that began about 541 million years ago and lasted until about 252 million years ago. During this era, there were several major events that shaped the Earth's history and led to the evolution of new life forms:
During the early part of the Paleozoic Era, there was a sudden burst of new life forms, including many of the major groups of animals that we know today. This is known as the Cambrian explosion.
Therefore, A) Paleozoic era, is the correct answer.

Describe how the size of the quadrat would impact population estimates. What limitations do you think exist for selecting quadrat size for field biologists?
Answer: There are different techniques used for population estimation in an ecosystem. Some include the use of quadrant, traps/foot prints, use of bisect and use of photograph among others. These techniques depend on the type of ecosystem involved.
Explanation: The formula used to estimate population using Quadrant method is given as:
N = (Area of sites x total number of individuals) ÷ (Area of the Quadrant x number of throws)
Note that, the area of the sites must have the unit as the area of the quadrant before you can use this formula.
Quadrants are used for actively mobile organisms and on a grassland ecosystem. They are not suitable for any vegetation that is not uniform or slant topography.

A person has a high fever of 105°F. State one effect that this high fever would likely have
on enzyme activity.
Answer:
The enzyme will change shape/denature, and stop activity
Explanation:
A person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.
What is the reason of high fever ?High fever (above 100F) is very dangerous for humans and can be fatal. One of the causes of this problem is the fact that high temperature modifies enzymes in the central nervous system which inducing the modification of the amino acid sequence of the enzymes.
With this given information, it is concluded that a person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.

where do chemical signals come from ?
Answer:
The nervous system at times utilizes chemical signals that are produced by an organ distant from the one being affected. For example, the hypothalamus produces releasing hormones that travel in a portal system to the anterior pituitary gland. Many chemical signals act locally-that is, from cell to cell.
Explanation:
Answer:
A sending cell produces chemical signals.
