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.

With over 600 muscles in the body we are able to do an array of motions. What is the difference between what big muscles, like the four in the quadriceps, can do and what those like the thirty in our hands can do?
The functions of each muscle depend on its location and ability to perform specific work. For example, the masseter muscle is the strongest muscle in humans which is present in the jaw.
What is the significance of muscles?The significance of muscle is understood by the fact that these structures are linked to bones, internal organs, and blood vessels. These components are responsible for movement by their contractions.
According to the context of this question, the muscles in the shoulder region are the four rotator cuffs which significantly include the supraspinatus, infraspinatus, teres minor, and subscapularis. The four muscles in the quadriceps have to perform a different function which includes heavy weightlifting, so, they have to strongest enough.
While the thirty muscles present in the hand can do numerous functions with different levels of intensity. These muscles are not too strong as compared to masseter but are superior.
Therefore, the functions of each muscle depend on its location and ability to perform specific work.

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 protein function listed here suggests that most enzymes are proteins?
A) provide structural support
B) transport substances inside the cell and between cells
C) communicate signals within the cell and between cells
D) speed up chemical reactions
E) control cell growth
The protein function listed here which suggests that most enzymes are proteins is that they speed up chemical reactions. That is option D.
Proteins are one of the classes of food that contains nitrogen in addition to carbon, hydrogen and oxygen.
Enzymes are those substances that helps in the breaking down of food substances into simple, soluble and diffusible substances before they can be absorbed into the body. It speeds up chemical reactions in the body by lowering the activation energy.
Enzymes are often referred to as proteins because proteins speeds up biological processes (chemical reactions) which is the same function performed by an enzyme in a living organism.

In mice, black color (B) is dominant to white (b). At a different locus, a dominant allele (A) produces a band of yellow just below the tip of each hair in mice with black fur. This gives a frosted appearance know as agouti. Expression of the recessive allele (a) results in a solid coat color. If mice that are heterozygous at both loci are crossed, ___ out of 16 will be black in color.
Answer:
3
Explanation:
Heterozygous mice at both loci would be BbAa genotype.
B (black) is dominant over b (white) but the presence of A results in agouti.
Crossing two heterozygous:
BbAa x BbAa
Progeny
9 B_A_ - Agouti
3 bbA_ - agouti
3 B_aa - Black
1 bbaa - white
Hence, 3 out of 16 progeny will be black in color.

Pablo and Johanna have to do a yearlong study for their biology course. After some discussion, they decide to try comparing their dogs and the diet that they feed them. Each has a dog from the pound, and both dogs are less than one year old. Pablo feeds his shepherd-mix dog a special diet of wet and dry foods from the local vet, while Johanna uses generic dry kibble from the supermarket for her bulldog. They want to see which diet results in bigger, healthier, faster-growing dogs. The reason the instructor gives them will include the fact that they have too many ______
Answer:
The correct answer is - variables that they didn't control and not enough replicates
Explanation:
In this particular case, Pablo and Johanna using too many variables in their experiment or research, All the variables used, are not controlled and with time these variables can not be replicated again on experiment groups.
They did not select a particular age or weight of dogs, the diets are different and they feed dry kibble to only one dog. There are so many variables and for a better result experiment, all variables should be controlled only the independent variable is permitted to manipulate.

The populations of which organisms will most likely increase as a result of a disease that suddenly reduced the population of Texas horned lizards?
F Grasses and ants
G. Ants and grasshoppers
H Grasshoppers and Texas cottonmouths
J. Texas cottonmouths and red-shouldered hawks
Answer:
G
Explanation:
It just is
Texas horned lizards primarily feed on ants, so if their population is suddenly reduced due to disease, the populations of their prey (ants) will likely increase.
What will they lead to if the population growth declines ?This, in turn, can lead to an increase in the populations of other organisms that depend on ants for food, such as grasshoppers.
Texas horned lizards are known to feed primarily on ants, and as predators, they play an important role in regulating the populations of their prey. When the population of Texas horned lizards is reduced, the ant population can increase, as there are fewer predators consuming them. This increase in ant population can lead to an increase in the populations of other organisms that depend on ants for food, such as grasshoppers.
Grasshoppers are herbivores that feed on vegetation, but they also feed on ants and other small insects. When the population of ants increases due to the reduction in Texas horned lizard population, the population of grasshoppers may also increase as they have more food resources available.
In contrast, Texas cottonmouths and red-shouldered hawks do not directly depend on Texas horned lizards as a food source, so their populations are unlikely to be significantly affected by a reduction in the population of Texas horned lizards.
Therefore, the populations of grasshoppers and ants (option G) are most likely to increase as a result of a disease that suddenly reduces the population of Texas horned lizards.

( ◑‿◑)ɔ┏--┑٩(^◡^ )Start a discussion on Homeostasis. List facts and opinions, then compare and contrast.
Answer:
- Homeostasis is the ability of living systems to maintain a steady and uniform internal environment to allow the normal functioning of the systems.
- It is the tendency to achieve equilibrium against various natural and environmental factors.
- Homeostasis results in a dynamic equilibrium, where continuous changes keep on taking place, and yet steady conditions are maintained.
- Homeostasis is mainly involved in managing various internal variables of the living system like body temperature, pH of various fluids, the concentration of different ions, and the body sugar level.
- A number of regulatory mechanisms are employed to resist changes in the body against environmental and bodily factors.
- Homeostasis can be maintained by separate organs or by the entire body at once.
Maintaining homeostasis/Homeostasis Mechanisms
Homeostasis is maintained by a complex system that consists of individual units working in a particular sequence to balance a given variable. All homeostasis mechanisms consist of four separate units, which are:
1. Stimulus
The stimulus is something that results in changes within the system involving the variable.
The stimulus represents that the variable has moved away from its normal range, initiating the process of homeostasis.
One example of this is the increased temperature of the body above 37°C due to various causes. The increased temperature indicates that the temperature of the body has gone higher than its higher range.
2. Sensor/ Receptor
The sensor or receptor is the sensing unit of homeostasis, where it monitors and responds to the changes in the body.
The changes in the system are realized by the sensor, which then sends the information to the control unit.
The nerve cells and receptors like thermoreceptors and mechanoreceptors are examples of sensor/ receptors.
3. Control unit
Once the information is sent to the control unit, it tallies the changed value to its normal value.
If the value is different from the normal value, the control center activates the effectors against the stimulus.
The thermoregulatory unit in the hypothalamus of the brain that controls the temperature of the body is an example of the control unit.
4. Effector
Effectors can be muscles, organs, glands, or other similar structures that are activated as a result of the signal from the control unit.
An effector is a target which is acted upon by the control unit to bring the value of variable back to normal.
The effector essentially counteracts the stimulus to nullify its effect.
In the case of thermoregulation, the sweat glands are effectors that are acted upon by the thermoregulatory unit to produce sweat so as to bring the value of body temperature back to its normal value.
How does the circulatory system work as a defense system?
Answer: It provides protection of the body by white blood cells, antibodies, and complement proteins that circulate in the blood and defend the body against foreign microbes and toxins. Clotting mechanisms are also present that protect the body from blood loss after injuries.
Answer:
The human circulatory system has a complex network of blood vessels that reach all parts of the body. This extensive network supplies the cells, tissues, and organs with oxygen and nutrients, and removes carbon dioxide and waste compounds.

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.
