The secondary mesophyll of leaves is made up of _______. A. parenchyma tissue B. collenchyma tissue C. sclerenchyma tissue D. parenchyma and collenchyma tissues

Answer:

B

Explanation:

We can predict that approximately 3166 species would occur in the entire 1000-hectare reserve based on the provided data and the species-area relationship.

To predict the number of species that would occur in the entire 1000-hectare reserve, we can use the species-area relationship and the values of c and z provided. The species-area relationship is typically modeled using a power law equation of the form:

\(S = cA^z\)

where S represents the number of species, A represents the area, c is a constant, and z is the slope of the relationship.

In this case, we have log(c) = 0.699 and z = 0.608.

To find the value of c, we need to take the antilog (base 10 exponentiation) of log(c). Therefore:

\(c = 10^{(log(c))\)

\(c = 10^{(0.699)\)

c = 4.997

Now we can use the equation \(S = cA^z\) to calculate the number of species for the entire 1000-hectare reserve. Substitute A = 1000 into the equation:

\(S = 4.997 * 1000^{0.608\)

S = 4.997 * 633.939

S = 3166.40

Explanation:

this is showing how the energy is distributed between the types of organisms in an environment

Answer: Chloroplast

Explanation:

Plants and some algae have chloroplasts responsible for photosynthesis. Plants undergo photosynthesis to transform light energy into chemical energy. This energy is stored in the form of sugar to support their growth and provide energy. Chloroplasts have a double membrane, with the thylakoid membrane located within the inner membrane.

Photosynthesis occurs within the thylakoid membrane, which is folded into sacs called thylakoids. Chlorophyll, a green pigment, is present in the thylakoids and it absorbs light energy to split water molecules into hydrogen and oxygen. The oxygen is released into the atmosphere while the hydrogen is used to create ATP, a molecule that stores energy. ATP and hydrogen are then utilized to make sugar, the final product of photosynthesis.

Chromosomes.

A chromosome is a thread-like DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibers in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.

There are 46 chromosomes in all, including 22 pairs of numbered chromosomes (autosomes) and one pair of sex chromosomes (XX or XY). Children receive half of their chromosomes from their mother and half from their father because each pair comprises two chromosomes, one from each parent. The dissolution of the nucleus during cell division allows for the visualization of chromosomes under a microscope.

The answer is A) tundra.

Answer:

Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.

Explanation:

Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.

According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.

Answer:

To increase the rate of the reaction in part C of the above image, change the temperature. Thus option C is correct.

At higher concentration of reactants, more collisions leads to increase the rate of the reaction.

Changing the pressure can change the concentration leads to high number of collisions caused increases the reaction rate.

If a reactant is a solid and  grinding of these reactants can increase the surface area, will lead to faster the reaction.

Increase in temperature, means molecule have higher average kinetic energy and more collision causes an increase in the reaction rate.

The medium in which the reaction occurs is another factor like in aqueous solution the reaction go faster.

Catalysts lower the activation energy followed by increase the rate of a chemical reaction.

Thus option C is correct.

When the rates of the forward and reverse reactions are equal. The system is dynamic because individual molecules react continuously. It is at equilibrium because no net change occurs.

Answer:

A system in dynamic equilibrium will have small changes that sum together to produce no net change.

Explanation:

Dynamic Equilibrium Definition

A system in dynamic equilibrium will have small changes that sum together to produce no net change. Many biological systems are in dynamic equilibrium, from the water inside a cell, to the dynamic equilibrium experienced by populations of predators and prey. Dynamic equilibrium is different from a static equilibrium, in which the parts do not move once they’ve reached equilibrium.

Dynamic equilibrium has different meanings in each science sub-discipline, such as biochemistry or ecology. In chemistry, the equilibrium of a reaction is the point at which the products and reactants have the lowest free energy. The dynamic equilibrium, on the other hand, is the point at which products are being generated as fast as they are falling apart. This may not be the same as the chemical equilibrium, as enzymes force many reactions far past their natural equilibriums by making products faster than they break apart. Due to this, chemist often refer to dynamic equilibrium as a dynamic steady-state, to clearly differentiate between the two points in a reaction.

Ecologists and population biologists will often refer to dynamic equilibrium when talking about populations of organisms. When studying the number of organisms in a population over time, many factors affect the growth of a population. Often, populations will go through periods of boom and bust. Ample resources cause high reproduction rates in all animals, leading to a much higher population. When the resources are distributed among this higher number, there are not nearly enough resources to go around. Thus, the population dies off. Ecologist see these cycles as a dynamic equilibrium that the population is stuck in, never really gaining or losing large numbers of individuals.

Examples of Dynamic Equilibrium

Glucose in an Organism

Throughout your entire lifetime, the glucose levels in your body remain relatively the same. Over the course of a day however, your body uses enormous amounts of glucose and must replace it. Each cell in your body requires glucose to function. As the cells use this glucose, the liver and your digestive system work quickly to replace it. Glucose from the food you eat is moved from the stomach and intestines into the bloodstream. The liver stores glucose as glycogen, and must break this large molecule down to release glucose into the blood. In your body, glucose is in dynamic equilibrium. While glucose has periods of high and low concentration, it is relatively stable. If glucose levels in your body fall out of dynamic equilibrium, or you cannot replace the glucose you use, you would eventually die.

Predator-Prey Dynamics

Ecologists often study the relationships between multiple species and their effects on each other. One relationship in nature that often shows dynamic equilibrium is the predatory-prey dynamic. Imagine a nature reserve that only contains rabbits and wolves. As the rabbit population increases, it provides more food for the wolf population. This sets both populations into dynamic equilibrium. The wolves, reaping the benefits of the increased rabbit population, also start to reproduce more. After a period of time, the wolf population also starts to increase dramatically. As more wolves are born and eat the rabbits, their populations eventually level off. The wolves, still reproducing at high levels, eventually start decreasing the rabbit population, which cannot keep up. The rabbits decrease, and eventually the wolves are left without enough food to support a large population. This dynamic equilibrium of both populations is interesting because it shows a direct cause and effect relationship between different species in an ecosystem.

It’s nice to be tall. Tall people are more likely to get hired, get promoted and are paid better than their shorter counterparts. They can reach things from high shelves, have unobstructed views at parades, and are consistently rated as being more attractive than others. Overall seems like a sweet deal.

If you are short, you get depressed when some points out that a study in the New England Journal of Medicine suggested that shorter people are at higher risk for heart disease. However, you might find some solace from a study published in PLOS one that found that shorter people lived longer or another study that suggested that taller people are at increased risk for cancer. When it comes to whether it is better to be tall or short, there is a lot of medical research on the subject, and one half contradicts the other half.

These studies get a lot of media play because they are instinctively popular. We are obsessed with height as a society. After all, we invented high-heeled shoes to defy genetics and punish our ankles.

But every time a report claims that taller is better (or that shorter is better), headline writers seem to consistently forget that six months ago they were claiming the opposite.

Plastic is defined as a material that contains an essential ingredient an organic substance of large molecular weight. It is also defined as polymers of long carbon chains. Carbon atoms are linked in chains and are produced in long-chain molecules.

Answer:

Plastic is a synthetic or semi-synthetic polymer material that is commonly used in the manufacturing of a wide range of products due to its versatility and durability. It is made up of long chains of molecules called polymers, which are formed by chemically bonding individual monomers (basic building blocks) together.

Plastic can be molded or shaped into various forms and can be made in a wide range of colors and textures. It is lightweight, strong, and relatively inexpensive to produce, which makes it ideal for use in many applications. Plastic can be found in everyday items such as water bottles, food containers, toys, electronic devices, and many other products.

While plastic has many advantages, it also poses significant environmental challenges. Plastic waste takes hundreds of years to break down and can accumulate in the environment, polluting waterways and harming wildlife. Some types of plastic also contain harmful chemicals that can leach into the environment and pose a risk to human health.

To address these challenges, there is growing interest in developing more sustainable alternatives to traditional plastic, such as biodegradable plastics made from renewable materials, as well as efforts to reduce plastic waste through recycling and other strategies.
