Summary
The life history of a species is the pattern of survival and reproduction events typical for a member of the species (essentially, its lifecycle).
Life history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction.
One tradeoff is between number of offspring produced and the amount of energy (both physical resources and parental care) put into each offspring.
What is the Defenition of Metabolism?
a
When offspring change and develop over millions of years
b
When living things change over time.
c
The flow of chemical energy in an organism.
d
When an organism produces an offspring
The answer is
C. The flow of chemical energy in an organism.
Metabolism is the chemical processes that occur within a living organism in order to maintain life.

pls make me brainliest
Explanation:
1. X-ray type electromagnetic radiation has higher energy than visible light and can pass through the human body.
2. Spectroscopy can provide composition and temperature information about objects in space.
3. Visible light is electromagnetic radiation with wavelengths between 380 nm and 700 nm.
4. Radio waves and ultraviolet light are examples of non-visible light.
5. When the emission line of helium from the galaxy is red-shifted as the galaxy is moving away from the viewer
The correct options for 1, 2, 3, 4 and 5 are A, (C and D), D, B and A respectively.
X-rays are valuable in medical imaging and other uses because they have more energy than visible light and can penetrate the human body.
By examining the light emitted or absorbed by the object, which forms a characteristic spectral pattern, spectroscopy can provide details about the composition and temperature of objects in space.
The human eye can perceive visible light because its wavelengths, which range from 380 nanometers to 700 nanometers, fall within this range.
Since their wavelengths lie outside the visible spectrum, radio waves and ultraviolet light are two examples of non visible light.
A galaxy is said to be moving away from the observer when the helium emission line from that galaxy is red-shifted in its spectrum. The Doppler effect, in which light emitted from objects moving away from the observer appears to be skewed toward longer (reddish) wavelengths, is what causes this redshift. This event is an important piece of evidence for the Big Bang theory and the expansion of the universe.
Therefore, the correct options for 1, 2, 3, 4 and 5 are A, (C and D), D, B and A respectively.

Answer:
Its summer, winter, darker.
Explanation:
This is the answer I hope it helps you out.
Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.
What are seasons?A season exists the year that stands determined by particular climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each includes its light, temperature, and weather designs that repeat yearly.
Summer exists the hottest of the four temperate seasons, happening after spring and before autumn. At or centered on the summer solstice, the earlier sunrise and latest sunset happen, daylight hours exist longest and dark hours exist shortest, with day length falling as the season progresses after the solstice.
Winter, the coldest season of the year, between autumn and spring; the name arrives from an old Germanic word that represents “time of water” and guides to the rain and snow of winter in middle and increased latitudes.
Hence, Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.

^ all the ansers
Explanation:
Cell membrane protects the cell and controls what enters and leaves the cell. So, the correct option is (C).
What is Cell Membrane?
The cell membrane is also called the plasma membrane. It is composed of a semipermeable lipid bilayer that regulates the transport of materials into and out of the cell. It protects the cell and provides a stable environment within the cell, and this membrane serves many functions.
The main function of the cell membrane is to transport nutrients into the cell, while another is to remove toxins from the cell. Cellular membranes are composed of glycerophospholipids, which are molecules composed of glycerol, a phosphate group, and two fatty acid chains.
Thus, Cell membrane protects the cell and controls what enters and leaves the cell. So, the correct option is (C).

What happens during S phase?
O A. Chromosomes are duplicated.
O B. DNA separates into two nuclei.
O C. The cell splits in two.
O D. Cytoplasm is manufactured.
Answer: A. Chromosomes are duplicated.
Explanation: This is the correct answer on the quiz.
Chromosomes are duplicated in S phase. Therefore, option (A) is correct.
What do you mean by S phase?
Between G1 phase and G2 phase, DNA replication takes place during S phase of the cell cycle. The processes that take place during S-phase are tightly controlled and highly conserved.
The cell replicates its genetic material entirely during the S phase of DNA synthesis; At the end of S phase, a normal diploid somatic cell with a DNA complement of 2N acquires a DNA complement of 4N.
DNA synthesis or replication occurs during the S phase of the cell cycle, which occurs prior to the interphase. Before entering mitosis or meiosis, the cell's genetic material is replicated in this manner, leaving enough DNA for daughter cells to divide.

Which of the following does NOT secrete hormones?
A. Ovaries
B. Skin
C. Adrenals
D. Pancreas
Answer:
skin acts as a protective barrier, therefore it does not secrete hormones
Skin does not secrete hormones. Thus, the correct option is B.
What are Hormones?Hormones may be defined as chemical substances that are produced by the organ system of an organism and transported at the site of action via the bloodstream. Hormones act as messenger molecules in the body.
Skin acts as the primary or first line of defense for the immune system. It does not secrete any hormones. It plays an important role in innate immunity. Ovaries are responsible for the secretion of hormones like estrogen and progesterone in females and regulate all the prospective consequences in the body of females.
The adrenal gland secretes hormones like cortisol and aldosterone which are steroid hormones. Such hormones are important in regulating metabolism, inflammation, immune functions, etc. The Pancreas secretes insulin and glucagon which play an active role in regulating the level of glucose in the blood.
Therefore, the skin does not secrete hormones. Thus, the correct option is B.

Removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat
What is Deforestation?Deforestation also known as forest clearance is defined as the removal of forest or stands of trees from land that is converted to non-forest use in which forest land is converted into farms, ranches or urban may involve converting to use. The most concentrated deforestation occurs in tropical rainforests.
It occurs when humans remove or thin forests for timber or use land where trees stand for crops, grazing, extraction such as mining, oil, or gas, or as populations grow and people move. Development takes place in the form of migration.
Wildlife habitats are fragmented due to deforestation, where native species have to live on remaining habitat islands that are surrounded by disturbed land being used for agriculture and other uses.
Thus, removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat
