Answer:
chloroplasts
Explanation:
chloroplasts
Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
Answer:
Chloroplast
Explanation:
photosynthesis takes place in chloroplasts
A certain species of trilobite is known to have lived 300 million years ago. If this index fossil was found in a rock layer containing other fossils, what could you infer about the other fossils
a The rock layer killed the trilobite and the other fossils
b The other fossils are about 300 million years old
c The organisms that formed the other fossils are still living.
d The rock layer formed before the trilobite and other organisms
Answer:
b The other fossils are about 300 million years old
Explanation:
From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.
Fossils are the preserved remains of organisms that has once lived. Through the principle of relative dating we can determine the age of fossils and those of other related ones. According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form". So, the fossils occurring together within the rock layers are of the same age.5. By about how much did average global temperatures increase from 1880 to
2020?*

Based on the picture above, what habitat is this bird best adapted for?
Forest
Ocean
Marsh
Desert
Answer:
I would have to guess forest, as those claws look like they are for grabbing hold of branches, and the long beak usually means they eat worms.

1 Invasive plant species affect the interactions of living and nonliving components
of an ecosystem, so the removal of invasive plants is often necessary. The goal of
most plant-control methods is to disrupt or inhibit the function of different plant
systems. For example, insects can be used to chew through roots in order to
reduce a plant's ability to absorb water.
Which of these functions would be most immediately affected by a reduction in water
uptake by roots?
A Disease resistance
B Seed dispersal
C Sunlight absorption
D Photosynthesis
Answer: photosynthesis
Explanation:
Answer:
D. Photosynthesis
Explanation:
I got it "Correct"
Which product is the result of light reactions in photosynthesis? O A. Water B. Glucose O c. Carbon dioxide OD. Oxygen
Answer:
D. Oxygen
Explanation:
Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.
Answer:
Oxygen
Explanation:
Both light dependent and light independent reactions in photosynthesis create glucose. But, only light dependent reactions convert carbon dioxide to oxygen.
Light independent: Carbon dioxide + water --> ATP and NADP(Energy/Glucose) and water
Light dependent: Carbon dioxide + water + light --> Glucose(ATP and NADP), water, and oxygen
5. Macromolecules which are both hydrophobic and hydrophilic and are a major
component of cell membranes are -
Answer:
All phospholipids have hydrophobic tails, consisting of the two hydrocarbon chains, and hydrophilic head groups, consisting of the phosphate group and its polar attachments. Consequently, phospholipids are amphipathic molecules, part water-soluble and part water-insoluble.

Predict how the inability of a species to adapt within a changing environment may contribute to the extinction of that species.
Answer:
B
Explanation:
What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.
Answer: Fearful and worried posture
Explanation:
Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.
When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).
All these tell that a dog is scared and worried or feeling tense.
Answer:
Defensive Threat Posture
Explanation:
Whale eye (whites of eyes showing)
Tail down or fully tucked
Piloerection
Ears back or flatten against head
Pupils dilated
Corners of mouth pulled back
Body lowered
Body leaning backward
A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?
A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.
C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.
D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.
I think it’s B, but I’m not completely sure. Help please!
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
Explanation:
The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.
With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.
Answer:
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Identify the 2 constructive processes from the list below.
A) A river wears away the land creating a canyon.
B) Over time a mountains top becomes less jagged and more rounded.
C) A volcano erupts and lava flows down its sides.
D) Silt is deposited at the mouth of a river.
Answer:
C, D.
Explanation:
C: The flowing lava creates extra rock. For example, entire islands are formed via this process of volcanos erupting, lava cooling, repeat.
D: Silt from erosion (erosion itself is considered destructive, but the resulting silt can turn into something constructive.) can build up entire mounds or mountains over time.

Which two animals are able to generate internal heat to maintain their body temperature in a coid environment
Parrots and Dogs are able to generate internal heat to maintain their body temperature in a coid environment. Parrots and Dogs are Endotherms. They generate most of the heat they need internally, when it's cold outside.
Does natural selection affect humans? How and why
Answer:
Yes it does affect humans.
Explanation:
Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. So natural selection acts on phenotype, but it is the connection to genotype that makes it the mechanism of evolution. Many traits vary among different members of a population of humans and animals, from body size to hair color, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. In scientific terms, these hazards are referred to as selection pressures. They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection "survival of the fittest" and it is how we evolved into the species we are today.
How does a destructive force differ from a constructive force?
Answer:
Destructive Forces break down features on the Earth's surface. Constructive Forces build up features on the surface of the Earth.
