How did New Zealand's early ecology affect which traits were selected for/against in the kakapo's ancestors?
Answer:
Hairy skin which helps kakapo's ancestors to live in harsh climate of New Zealand.
Explanation:
New Zealand's early ecology greatly affected the population of kakapo's ancestors because the environmental conditions for kakapo's ancestors are favourable and there is no invasive species which reduces the population of kakapo's ancestors near to extinction. The traits that were selected for the kakapo's ancestors provides ability to live and survive in the temperate and subtropical climates of New Zealand. The flightless trait in this bird is also responsible for its extinction because this bird can't run away from their predators.
The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.
Answer:
In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.
A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response

Which of the following is not an appropriate unit for momentum?
A. g • cm/min
B. g • m/S
C. km • m/S
D. kg • m/hr
Answer:
Option C us correct.
km • m/S
Explanation:
This is because momentum is result of mass and velocity of an object. Momentum is a vector quantity that is it has magnitude and it's direction is in form of three dimensional.
From the option C, kilometer there is not a unit for mass or velocity it it is a unit for distance, therefore it is incorrect.

how would the solar eclipse be different if the moon was moved AWAY from the earth?
Answer:
The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

No decorrer das semanas, a lua apresenta diferentes aspectos. A causa para essas mudanças na aparência do satélite da terra é: A) a sombra da terra refletida sobre a lua. B) o movimento de rotação da lua em torno do seu próprio eixo. C) os raios solares que incidem na superfície da lua. D) a translação da lua ao redor da terra.
Answer:
C) the sun's rays that fall on the moon's surface.
Explanation:
The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.
What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?
Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

Joseph sets up an experiment growing corn in three containers. Each container has the same amount of
potting soil and fertilizer. Each corn plant is five centimeters (cm) tall. The containers are all placed so thatthey
receive the same amount of light. All of the plants are grown at the same temperature. The plants are
watered once a week: container #1 receives 10 ml of water, container #2 receives 20 ml of water, and
container #3 receives 30 ml of water. Joseph measures the growth of each plant for six weeks.
Which hypothesis is being tested?
The amount of water supplied will affect plant growth.
The temperature will affect plant growth.
The type of fertilizer will affect plant growth.
The amount of light exposure will affect plant growth.
Answer:
The amount of water supplied will affect plant growth is the hypothesis being tested.
Explanation:
Because that is the only variable being altered or changed, every other variable remains consistent. In any experiment what your testing is what's altered between each subject or test group.
List the three parts of the cell cycle.
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Explanation:
State the function of Bowman's capsule and glomerulus.
➜ Bowman's capsule and glomerulus have semipermeable walls.
The glomerulus, is a tuft of capillaries contained in Bowman's capsule.The water and dissolved substances (wastes and useful) are filtered into the Bowman's capsule and from here they are filtered into the tubule.Thus, both the structures act as filtering apparatus.Complete the chart. Thymine _____, Guanine ____.
Answer: 27, 23
Explanation: Thymine goes with Adenine and together they equal 50 so Thymine would be 27 because Adenine is 23. Same with Cytosine and Guanine. They go together and equal 50 so Guanine would be 23 because Cytosine is 27. Hope this helps!

1. What is the gradual change in populations over time?
2. What is the idea that species originate in small gradual steps over time?
1. Gradualism
2. evolution
Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.
2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).
Explanation:
Si se aplica a un muelle una fuerza de 30N provocamos que se alarguen 0.2m . Calcular la constante del resorte. Y que fuerza que habra que aplicarle para que se alargue 0.45m
Answer:
I. Constante de resorte, k = 150 Nm.
II. Fuerza = 67.5 Newton.
Explanation:
Dados los siguientes datos;
Fuerza, F = 30 N
Extensión, e = 0.2 m
Para encontrar la constante del resorte;
Fuerza = constante de resorte * extensión
F = ke
30 = k * 0.2
Constante de resorte, k = 30 / 0.2
Constante de resorte, k = 150 Nm
A continuación, para encontrar la fuerza para una extensión de 0,45 m;
Fuerza = 150 * 0.45
Fuerza = 67.5 Newton.

Answer:
While all compounds are molecules, not all molecules are compounds. A molecule is formed when two or more atoms of an element chemically join together.
Explanation:
Human Immunodeficiency Virus (HIV) is a virus that infects (and destroys) Helper T Cells. As a result, people who are HIV+ generally have a low number of these T Cells. How would the dramatic decrease in Helper T Cells caused by HIV affect a person’s immune response? Be specific using details from what you learned about the immune response.
Answer:
HIV invades various immune cells (e.g., CD4+ T cells and monocytes) resulting in a decline in CD4+ T cell numbers below the critical level, and loss of cell-mediated immunity − therefore, the body becomes progressively more susceptible to opportunistic infections and cancer.
HIV infects and deletes CD4+ T cells that normally coordinate the adaptive T- and B-cell response to defend against intracellular pathogens. The immune defect is immediate and profound: At the time of acute infection with an AIDS virus, typically more than half of the gut-associated CD4+ T cells are depleted, leaving a damaged immune system to contend with a life-long infection.
