A cell removes a toxin it has produced through a chemical reaction. Which characteristic of living things is the cell demonstrating?
the ability to maintain homeostasis
the ability to maintain homeostasis
the ability to grow and develop
the ability to grow and develop
the ability to adapt and evolve
the ability to adapt and evolve
the ability to reproduce
Answer:
Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.
According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.
Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.
Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.
a. Gene theory
b. Homeostasis
B
An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.
False
False
Humans began life as a single cell because we develop from a fertilized egg cell.
Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.
No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.
Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.
Answer:
How the structures of plant tissues and organs are directly related to their roles in physiological processes.
o Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.
o Physiological processes are limited to photosynthesis, cellular respiration,
transpiration, and reproduction.
o Plant tissues are limited to meristematic, ground, dermal and vascular tissues.
o Plant structures are limited to cambium, guard cells, phloem, seed, stomata and
xylem
Explanation: Hope this helps have a safe and happy new year
Roots, stalks, leaves, flowers, fruit, and cones are the only organs found in plants. Photosynthesis, metabolic processes, transpiration, and fertilization are the only physiological activities.
Plant and plant tissues:Photosynthesis and the movement of mineral-containing water ions are critical processes in the development of healthy plants. Plants have three primary structures or organs:
LeavesStemsRootsThey're made up of groupings of specialized tissues with structures that are tailored to the functions they do.
Adaptations are distinctive features that help plants survive in their specific settings. Plants rely on their specialized structures to provide their fundamental requirements, protect themselves from predators, and aid reproduction.

In the graph below, which letter represents the activation energy of a catalyzed reaction and why?
Choose 1 answer:
(Choice A) Y; the activation energy is reduced in a catalyzed reaction
(Choice B) X; the activation energy is greater in a catalyzed reaction
(Choice C) X; the activation energy is greater in an uncatalyzed reaction
(Choice D) Y; the activation energy is greater in an uncatalyzed reaction
Report a problem
Answer: Choice C) X; the activation energy is greater in an uncatalyzed reaction
Explanation: I got this question on khan academy.
The option that represents the activation energy of a catalyzed reaction is C. X; the activation energy is greater in an uncatalyzed reaction.
Activation energy simply means the minimum amount of energy that should be provided for compounds that'll result in a chemical reaction.
It should be noted that the activation energy for uncatalyzed conversion to the products will be more than that of the catalyzed reaction. In this case, X; the activation energy is greater in an uncatalyzed reaction.

How is mRNA produced during the process of DNA transcription
Answer
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

Which organelle plays an important role during mitosis, helping to move chromosomes around the cell
a
Oь
Ос
Od
vacuoles
Golgi bodies
chloroplasts
centrioles
Answer:
Explanation:
Duplicated centrioles are responsible for moving chromosomes during mitosis.
They are involved in the formation and organization of spindle during cell division (mitotic phase) and also in the process of cytokinesis.
It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.
Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.
They originate from the poles of the cell by the organelle called centriole, and attached to the kinetochore of the chromatid.
Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.
These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.
During anaphase they are shortened, which pulls the chromosomes to the opposite poles separated from the pairs.
At the end in telophase, where nuclear membrane becomes visible it disappears.
In this way the spindle fibers help in the separation of chromosomes into two new daughter cells. This process is also known as the distribution of heredity or genetic information between new cells.

Which part of the carbon cycle occurs when plants, trees, or fossil fuels are burned?
A. Transpiration B. Oxidation C. Photosynthesis D. Combustion
Answer:
Combustion.
Explanation:
It's just as it sounds, combustion is the process of burning something. In the carbon cycle, combustion occurs whenever any organic living or non-living thing is burned in the proximity of oxygen, afterwards producing carbon dioxide.
Combustion is the part of the carbon cycle which occurs when plants, trees, or fossil fuels are burned. Thus, the correct option is D.
What is Combustion?Combustion or burning is a high-temperature exothermic redox chemical reaction which occurs between a fuel and an oxidant. The oxidant is usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. This is one of the major reasons of pollution.
Three main types of combustion include rapid combustion, spontaneous combustion, and explosive combustion.
Therefore, the correct option is D.

A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.
