Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.

In around 50 years, the peppered moth population changed from nearly all light wings to nearly all dark wings. Explain exactly how the moth population changed (evolved).
Answer:
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. ... Later, when pollution was reduced, the light-coloured form again predominated.

Once ice forms on a lake in winter, the water underneath the ice remains about 4 c even if the air temperature just above the ice far below freezing. What property of water helps keep the water below the ice from freezing?
Answer:
Hydrogen bonding. When the ice freezes, it becomes less dense and floats to the top. this insulates the water keeping it from freezing.

The body temperatures of ectotherms, like lizards and turtles, can fluctuate with the environment. How do ectotherms maintain homeostasis?
Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat to maintain their body temperature but take on the temperature of the environment.

"The chicken genome has about 17,000 genes, and the grape has about 30,000 genes." Which claim about human genes would be most strongly supported by this statement? A. The number of human genes is not especially large compared to other organisms. B. Humans have many more genes than other species. C. Humans are genetically very similar to other species and differ by only a few key genes. D. Humans are genetically very different from other species and share few if any genes with them.
Answer:A
Explanation: I took the quiz.
The claim about human genes would be most strongly supported by this statement is, that the number of human genes is not especially large compared to other organisms.
What do you mean by Genes?Genes may be defined as a stretch of DNA that helps in the determination of each characteristic specifically.
According to the human genome project, humans have 20,000-25,000 genes. while the tiny eater flea Daphnia has the most genes of any animal which is 31,000.
Therefore, the claim about human genes would be most strongly supported by this statement is, that the number of human genes is not especially large compared to other organisms.

How do you think new proteins affect the fitness of children?
Answer:
it affects ALOT!
Explanation:
Although health initiatives promote increased physical activity in children, the physiologic outcomes have not been well characterized. This investigation examined the effects of programmed aerobic exercise on protein metabolism in children (n = 7; mean ± SEM: 9.14 ± 0.46 y old; weight, 32.1 ± 1.6 kg; height, 138 ± 2.5 cm; and body mass index, 16.21 ± 0.36 kg/m2 ) using 15N-glycine methodology. Boys (n = 5) and girls (n = 2) walked (5 d/wk, 3.2–6.4 km/d) for 6 wk. Criterion measures taken at baseline (Pre) and after the exercise program (Post) included anthropometric data, dietary assessment, nitrogen balance, nitrogen flux (Q), protein synthesis (PS), protein breakdown (PB) and net protein balance [(Net) = PS − PB]. After the walking program, there were no significant changes in body weight, fat-free mass or percentage of body fat, whereas height increased (P < 0.01). Energy and protein intakes were constant throughout the study. Nitrogen balance was significantly more positive Post than Pre (P < 0.05). There was a significant decrease in Q (P < 0.0001) with corresponding decreases in PS (P < 0.001) and PB (P < 0.01). These data provide the first evidence that programmed aerobic exercise alters whole-body protein utilization in healthy, nonobese children. Longitudinal studies are required to further examine changes in protein metabolism associated with increased physical activity in this population. In addition, findings suggest a need to evaluate nutrient requirements for healthy, physically active boys and girls.

Answer:
i think glacial horn is an example of a glacial formation?
Glacial Horn is a pointed peak like feature which are bounded on at least three sides by glaciers. Thus, glacial horn is a best example of glacial formation. Hence, option A is correct.
What is Glacier?
Glacier is a slow moving mass of ice observed in the high mountain valleys and colder Polar Regions.
Every mass of ice are not glacier, it must be at least six hundreds of a square mile in size and the thickness will be more than 164 feet.
The principal components for the formation of glacier is snow.
Hence it is observed during winter in the regions where a lot of snow fall occurs and less snow will melt in summer.
Glacial horn are specifically have flat faces which show a pyramidal shape and sharp distinct edges like a pointed peak structure.
Hence, option A is correct.

Explanation:
When an action potential is generated within a motor neuron, ________. When an action potential is generated within a motor neuron, ________. all of the muscle cells within the motor unit are stimulated to relax the muscle cells from a neighboring motor unit will contract every muscle cell of the motor unit is stimulated to contract only select muscle cells within the motor unit are stimulated to contract the muscle cells of the motor unit will occasionally contract
Answer:
every muscle cell of the motor unit is stimulated to contract.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.
For example, opening the door of a microwave oven as soon as its timer beeps.
Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.
Action potentials generates the nerve impulse in a motor neuron.
When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.
There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you eat to replenish the energy you spend walking for 2 hours?
Answer:
to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten
Explanation:
Firstly, let us calculate the number of calories burnt in 2 hours
in 10 minutes; 30 calories are burnt
∴ in 1 minute 30/10 calories are burnt = 3 calories are burnt
2 hours = 120 minute
∴ in 120 minutes 3 × 120 = 360 calories are burnt.
Next, let us calculate the amount of trail mix that contains 360 calories
100g of trail mix = 450 calories
450 calories = 100 g
1 calory = 100/450
∴ 360 calories = 360 × (100/450)
= 360 × 0.222 = 80g
∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten
