Answer:
In the reaction of decomposition of hydrogen peroxide (H₂O₂), catalase is the enzyme responsible for catalyzing this reaction.
Explanation:
Catalase is an oxide-reductase enzyme whose substrate is H₂O₂, a potentially harmful by-product of metabolism.
The reaction that is mediated by catalase is:
H₂O₂ ------catalase--- → 2H₂O + O₂
where catalase is the enzyme that breaks the bond of the additional oxygen in the molecule to obtain H₂O and free O₂.
People with catalase deficiency may experience disorders and diseases due to the accumulation of H₂O₂ in the body.

How does a lion get its source of nitrogen to form its DNA or proteins?
Answer: The protein in their diets
Explanation:
The lion gets its source of nitrogen to form protein in its diet.
What is protein?Proteins are macronutrients that are present in foods. There are two types of proteins. Essential and nonessential. Non-essential proteins are synthesized in the body and essential proteins are needed to eat by taking food.
A lion is an animal, and animals synthesize some proteins in their body, and some proteins are to be taken from the food. Protein is necessary for the growth of the body. It gives strength to the body.
The protein synthesis is done in the cell of the animals. But the nitrogen, that the animals get is from the diet they eat which is meat and plants. It depended upon its diet. Some animals are carnivorous and some are herbivorous.
Therefore, the lions get their protein from their diet.

Why is it logical for the level of FSH to fall greatly following ovulation?
Answer:
During each menstrual cycle, there is a rise in follicle stimulating hormone (fsh) in the first half of the cycle that stimulates follicular growth in the ovary. After ovulation the ruptured follicle forms a corpus luteum that produces high levels of progesterone. This inhibits the release of fsh!
A student claims that the monarch population increases and decreases in a cycle, similar to the pattern of predator-prey populations like wolves and moose. Use the data to evaluate this claim
Answer:
yes that is true because by looking at the graph you can tell that it starts to increase then slowly decrease.
Explanation:
The monarch population represented by the graph depicts a fluctuating pattern which epitomizes a rise and fall pattern in the area occupied by monarchs over the winter season between 1995 and 2005.
The predator-prey population depicts the sharp decline in the prey population as they are being fed on in large numbers as the number of predator multiplies. This is followed by a decrease in the number of predators due to starvation as the available prey are insufficient to cater for their number. The cyclic nature of the graph shows similar pattern as areas occupied by monarchs declines as the winter season progresses over time.Learn more :https://brainly.com/question/18576344?referrer=searchResults

A trait such as having a crooked thumb is produced by a (n)
A Hitchhiker thumb or crooked thumb is produced by recessive alleles. It is an example of a rare genetic disorder.
What is Hitchhiker's thumb?Distal hyperextensibility of the thumb is another name for a hitchhiker's thumb. This is caused by the hereditary characteristics that lead a person to stretch while bending his thumb backward.
The distal joint is crucial in maintaining the thumb's straightness. The thumb can bend backward, becoming the hitchhiker's thumb, when the distal joint hyperextends. A hitchhiker's thumb is neither a benefit nor a drawback.

A. After 76,000 years all the nickel 59 in a rock decays in the cobalt 59
B. Nickel 59 can only be used to date rockstar younger than 76,000 years
C. All the nickel 59 stabilizes after he completes 1/2 life. Of 76,000 years
D. The amounts of nickel 59 and cobalt 59 remain the same over a half life period
E. The amounts of nickel 59 in cobalt 59 tell how long ago the rock cool to closure temperature
Answer: C.
Explanation:
The amounts of nickel 59 and cobalt 59 remain the same over a half life period. So, the correct option is (D).
What is Half-life?The half-life of an isotope is described as the period in which half of the amount of the isotope has decayed and half of its original amount is present. Half-life is defined as the time required for a quantity to reduce to half of its initial value.
It is used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms live. This is usually the case to characterize any type of exponential decay.
[tex]t_1_/_2= 0.693/k[/tex]
Where, [tex]t_1_/_2[/tex]= half life of the isotope
k = Decay constant
Nickel-59 has a half-life of 76,000 years, meaning that the time it takes for the isotope's original mass to decrease to half of its original volume is 76,000 years which means that amount of nickel-59 left to be decayed is equal to the amount of nickel-59 decayed into cobalt-59.
Thus, the amounts of nickel 59 and cobalt 59 remain the same over a half life period. So, the correct option is (D).

A. the size of the molecule
B. the chemical properties of the molecule
C. the charge of the molecule
D. All of the above
Whether a molecule can cross the plasma membrane depends upon D. All of the above
Which molecule can pass the plasma membrane?
Small nonpolar molecules, consisting of O2 and CO2, are soluble in the lipid bilayer and consequently can effectively cross cell membranes. Small uncharged polar molecules, which include H2O, can also diffuse thru membranes, however large uncharged polar molecules, inclusive of glucose, cannot.
How do molecules pass across the plasma membrane?Explanation: Molecules pass throughout the plasma/mobile membrane through diffusion. If they're not small sufficient, they need to break down by means of other substances, which include enzymes, which can be biological catalysts. If they are small enough, usually, the easiest way for them to move is through diffusion.

Answer:
B is one of the correct answers.
Explanation:
Mine has multiple answers but if yours doesn't I hope this helps!
The tentacles of an octopus and the limbs of a lizard are analogous organs. So the correct option is B.
What are analogous organs?The organs possessed by different species which have different anatomical structures but perform the same function as one another are called analogous organs. The development of analogous organs is a form of convergent evolution.
In convergent evolution, different types of species evolve separately and independent of each other but at some point, their functions or the functions of their organs converge with one another.
These analogous organs are developed in totally unrelated species but due to their environment, their evolution works in such a way that they develop in a similar way even after sharing no similarities with each other.
The convergent evolution giving rise to analogous organs is called homoplasy in terms of cladistics.
Thus, the tentacles of an octopus and the limbs of a lizard are analogous to each other. Therefore the correct option is B.

In 1815 a volcano erupted spewing billions of tons of ash into the sky. This ash "cloud" caused global annual temperatures to drop below normal, causing "a year without a summer" in 1816.Which sphere did this ash "cloud" affect to cause these changes? *
Answer:
The Atmosphere
Explanation:
1816 was a year without summer because the billions of tons of ash that was spewed blocked radiation preventing it from reaching the surface of the earth.
A volcano is a break in the crust of planetary bodies like Earth that allows gasses, volcanic ash, and hot lava to escape. Volcanos are one of the major factors that cause climate changes on Earth mostly because of their cooling effect.
The ash, gasses and lava usually escape to the atmospheric layer of the earth with their cooling effect. And they cool the earth by blocking incoming solar radiation. This can go on for months or years depending on the components and severity of the eruption and can lead to "a year without summer" as witnessed in 1816.
