Answer:
Immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or another unwanted biological invasion, while having adequate tolerance to avoid allergy and autoimmune diseases. Each part of the immune system has a unique function. Also, the immune system is responsible for down-regulating immune responses against external harmless triggers such as food, or against the bodies' tissue. Active immunization is the induction of immunity after exposure to an antigen. Antibodies are created by the recipient and may be stored permanently. Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response. And passive immunity is the transfer of active humoral immunity of ready-made antibodies. Passive immunity can occur naturally when maternal antibodies are transferred to the fetus through the placenta. Passive immunity refers to the transfer of antibodies from one individual to another.

What type of growth is characterized by a consistent increase in growth rate?
A) Exponential growth B) Carrying capacity growth
C) Logistic growth D) Stable growth
Answer:
It is Exponential growth.
Explanation:
Carrying capacity is the most amount of each population that a ecosystem can hold.
Logistic growth is not consistent.
The type of growth that is significantly characterized by a consistent increase in growth rate is known as Exponential growth. Thus, the correct option for this question is A.
What is Exponential growth?Exponential growth may be characterized as a type of growth that is followed by continuous breeders. The population of continuous breeders contains more individuals than a similar population breeding annually.
Some examples of this growth pattern include insects, humans, bacteria, internal parasites, larger plants, and animals. In this type of growth pattern, the value of carrying capacity must be reached fat as compared to other growth patterns like logistic growth.
Therefore, exponential growth is a type of growth that is significantly characterized by a consistent increase in growth rate. Thus, the correct option for this question is A.

Suri designed an experiment to plant lima bean seeds. Her variable was to change what kind of light each plant received. She used
a different kind of light with each plant. She hypothesized that the plant grown under the natural sunlight would have the greatest
amount of growth. What can she conclude after the results of her experiment?
A) photosynthesis does not require any light for a plant
B) plants grow best when they are grown under a black light
C) photosynthesis can happen under lights that are not the sun
D) plants cannot grow unless they are exposed to natural sunlight
Answer:
Option C
Explanation:
Light from the sun (sunlight) is the most suitable form of light energy that necessary for plant growth and blooming, but artificial light can also be useful in helping plants grow. For example, low-light foliage plants such as the peace lily can grow quite readily in offices that do not have windows with just about enough artificial light.
Answer:
The correct answer is C: "photosynthesis can happen under lights that are not the sun"
Explanation:
A) photosynthesis does not require any light for a plant. This is not correct, as in order to photosynthesize any plant need light. In its absence, the plant does not obtain any energy and is not able to produce organic matter.
B) plants grow best when they are grown under a black light: This is not correct because, in comparison with other lights of different colors, plants grown under a black light are ones that show the less growth rate.
C) photosynthesis can happen under lights that are not the sun: This is correct. Photosynthesis can indeed occur under other lights. There are different factors to take into count if we want plants to grow under artificial conditions, such as the amount of light, times of light per day and the color of the light.
D) plants cannot grow unless they are exposed to natural sunlight: This is not correct. Although sunlight is the best option for any plant to grow in the correct time and form, these organisms might also grow under artificial lights of different colors or wavelengths. The plant might respond in different ways, depending on the light it is exposed to, but eventually, it will show some growth.

Were the offspring of this organism uniformmeaning they look the same as each other and the parent, or were they diversemeaning they express a variety of appearances? Explain your answer.
Answer:
Uniform
Explanation:
Complete question -
The organism reproduce asexually. Were the offspring of this organism uniformmeaning they look the same as each other and the parent, or were they diversemeaning they express a variety of appearances? Explain your answer.
Solution
It is given that the organism is reproducing asexually; hence its entire offspring will have resemblance to their parent as well as among themselves. There is no scope of genetic variation in asexually producing offspring. However when an organism undergo sexual reproduction, there are high chances of it producing offspring with varied characteristics as the parents gamete carry genes of ancestors and allows for various recombination. Unlike sexual reproduction, the organism producing asexually produces similar gametes and hence offspring one generation after the other.

Answer:
D. To show condensation, you add energy to change water vapor into liquid water; to show evaporation, you add energy to change liquid water into water vapor.
When condensation occurs, gas turns to liquid, and when evaporation occurs, liquid turns to gas.
B. could also be correct, but D. seems to be the better fit.
Answer:
To show condensation , you must decrease the temperature within the cycle ; to show evaporation , you must increase the temperature .
Explanation:
Condensation : condensation is nothing but the change of water vapour into liquid water . it happens when the water vapour reaches from a hot area to a cold area . for instance ~ when you pour hot tea in a cup and cover it with a plate. after few seconds you would see droplets of water there . this means that the water vapour which was in liquid form , when touched the cold surface of plate , it changed into liquid water .
Evaporation : It is the conversion of hot liquid into water vapour . just reverse of above phenomena .
