Answer:
Older fossils are found in deeper layers of sedimentary rock.
Explanation:
The relationship between undisturbed sedimentary rock layers and fossils is that older fossils are found in deeper layers of sedimentary rocks.
This is one of the premise of the law of superposition and principle of fossil and fauna succession.
An undisturbed sequence is one in which the sedimentary layers have been arranged sequentially. The oldest is at the bottom and the youngest on top. Also, fossils grade in this manner too. The oldest fossils will be in the oldest bed which is the deepest layer. The youngest bed will contain the youngest fossils in like manner too.Compared to worms, insects are highly responsive to environmental stimuli. Identify 2 external nervous system adaptations shown that make this possible in the insect?
Answer:
Eyes, Antenna and Hairs on their cuticle
Note: There are no diagrams or attachments provided.
Explanation:
Eyes
The eyes of insects serve the function of vision. Insects eyes are of two kinds; simple eyes or ocelli, and compound eyes. The simple eyes or ocelli can sense only light, darkness, and movement. The compound eye which consists of individual light receptive units called ommatidia can distinguish brightness and colour. More ommatidia in an insect's compound eye results in more clarity of vision
Hairs
Tiny hairs known as setae found all over the cuticle of insects are sensitive to vibration touch and sound and therefore serve as sense organs of touch and sound for insects.
Antenna
The antenna in insects serves various sensory functions such as sensing touch, air motion, heat, vibration (sound), and especially smell or taste.

Which of the following correctly states the roles of the xylem and guard cells in the
process of photosynthesis?
Answer:
Plants convert energy from sunlight into sugar in a process called photosynthesis each plant contains a branched system of tubes called xylem which is responsible for water transport from the roots (where it is taken up) to the leaves (where it is used in photosynthesis).

What are forces and how do they affect the motion of objects?
Explanation:
Force is describe as a push or pull on a body. It causes the motion of a body generally.
Newton's law of motion greatly explains the synergy between force and motion. A body will maintain its position at rest or uniform motion unless if it is acted upon by an external force. When force acts on a body, there is a considerable change in the motion of the body.How does geoscience processes and current human activities affect resources in a swamp?

An Important step in the process of translation is
Answer:
The steps in translation are:
The ribosome starts matching tRNA anticodon sequences to the mRNA codon sequence. The ribosome continues until it hits a stop sequence, then it releases the polypeptide and the mRNA. The polypeptide forms into its native shape and starts acting as a functional protein in the cell.
Explanation:
Dogs and wolves are more closely related to each other than either is to cats.
Explain how you would separate these organisms into clades.
Answer:
I would split these organisms into two paraphyletic groups: 1-one group composed of wolfs and dogs, and 2-one group including all three species (dogs, wolves and cats).
Explanation:
A clade is by definition a monophyletic group, it means that a clade is a group composed of a common ancestor and all its lineal descendants. Moreover, a paraphyletic taxon is a group of organisms that share a most recent common ancestor and some of its descendants. In this case, wolves and dogs can be grouped to form a more inclusive group since both species belong to the same genus (Cani), while dogs, wolves and cats can be grouped to form a major group because these three species are mammal species. In consequence, in this case, we have two paraphyletic groups supported by synapomorphic (shared, derived) characters, since wolfs and dogs represent only two species within genus Canis, while dogs, wolves and cats represent three species within class Mammalia.
________ proteins or channel proteins are used to aid substances across the cell membrane in passive transport
Answer: channel proteins
Explanation:

state the role in the menstrual cycle of the following hormones, FSH, LH, estrogen and progesterone
Answer:
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are called gonadotropins because stimulate the gonads - in males, the testes, and in females, the ovaries. They are not necessary for life, but are essential for reproduction.
Explanation:
The function of estrogen & progesterone is Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone. Estrogen and progesterone stimulate the uterus and breasts to prepare for possible fertilization.
Explain the relationship between the number of daylight hours and seasons.
Explanation:
The tilt of the Earth's axis also defines the length of daylight. Daylight hours are shortest in each hemisphere's winter. Between summer and winter solstice, the number of daylight hours decreases, and the rate of decrease is larger the higher the latitude. The fewer sunlight hours the colder the nights.
blood from all the parts of the body except the lungs goes to the _____ of the heart
Answer:
The aorta is the main artery that carries blood from the heart to all parts of the body EXCEPT the lungs.
Explanation:
1. The cells in our bodies are surrounded by these types of solutions.
3. When an animal cell is places in this solution, it will burst (get layer)
4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller).
5. This is a solution with more solute than the cell.
A) isotonic solution
B) hypertonic solution
C) hypotonic solution
Answer:
1. The cells in our bodies are surrounded by these types of solutions. → Isotonic solution.
3. When an animal cell is places in this solution, it will burst (get layer) → Hypotonic solution.
4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller) → Hypertonic solution.
5. This is a solution with more solute than the cell. Hypertonic solution.
Explanation:
The cells in the body are in a balance of substances —concentration of solutes— between their cytoplasm and the extracellular space. This balance is dynamic in living beings, due to the constant exchange of ions and substances between the intracellular and extracellular space. For this reason, the extracellular medium is isotonic with the cytoplasm.
A cell can lose or gain water depending on the amount of solutes that a medium has in which it is found, with respect to the cytoplasm. This difference in solutes concentrations produces an osmotic gradient that drags water from the least concentrated solution to the most concentrated, through the process of osmosis, which seeks to achieve an equilibrium of concentrations.
When a animal cell is exposed to a hypertonic solution —with a higher concentration of solutes— it loses water and tends to dehydrate and become smaller.An animal cell in a hypotonic solution receives water, so it can expand and even burst.In practice, the concentrations of intracellular and extracellular solutes depend not only on the osmotic gradient, but also on the concentration gradient of substances.

ill give you a brainliest if it is right
Answer:
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
magma-hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
igneous rocks- Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.
