how do neurons transmit signals throughout the body?
Answer:
When neurons communicate, an electric impulse triggers the realease of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side ,called receptors. Receptors are located on the dendrites. Receptors receive And process the messages

What happens in the light reaction of photosynthesis?
What happens in the dark reaction of photosynthesis?
What five factors affect photosynthesis and its rate? How?
Answer:
Ans - 1 Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast.
Ans-2 The dark reactions of photosynthesis occur in the stroma of the chloroplast where they utilize the products of the light reaction. In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.
Ans-3 The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

How would you describe symmetry in invertebrates?
Answer:
Invertebrates can have bilateral or radial symmetry, or they can be asymmetrical. Bilateral symmetry means that the animal is arranged in the same way on both sides. Radial symmetry means the body parts are arranged in a circle around a central point.
What did the first cells form from? What kind of cells where
they?
Answer:
The first cells were most likely primitive prokaryotic-like cells, even more simplistic than these E. coli bacteria. The first cells were probably no more than organic compounds, such as a simplistic RNA, surrounded by a membrane.

A scientist is studying trace fossils of an early mammal. Which type of informatin can be learned from studying
trace fossils?
how many teeth the mammal had
the structure of the mammal's skeleton
information about the behavior of the mammal
how the mammal is related to modern mammals
Answer:
Studying the trace fossils allows scientists to determine how the animal moved, whether it traveled alone or in groups, the environment in which it lived in, an organisms feeding habits or nesting behavior, and their feces, known as profiteroles, can provide information about an organism's diet.
Explanation:
hope it helps
The environment in which the organism lived, its feeding habits or nesting behavior, and their feces, known as profiteroles, can reveal information about an organism's nutrition are all things that can be learned through studying trace fossils.
What types of information do we get from trace fossils?Instead of the preserved remnants of the actual animal's body, trace fossils offer us indirect proof of life in the past in the form of animal footprints, tracks, burrows, borings, and feces.What information can scientists gain from trace fossils?Paleontologists can learn about the activity of ancient species by studying trace fossils. For instance, studying dinosaur footprints has greatly improved our knowledge of their behavior.What are two types of trace fossils?The majority of known trace fossils come from marine strata. There are basically two different kinds of traces: exogenic traces, which are created on the sediment's surface (like tracks), and endogenic traces, which are created within the sediment's layers (such as burrows).

Answer: Your answer is Sexual reproduction
Explanation:
The sperm and eggs produced with sexual reproduction provide genetic diversity because their gene combinations differ from those in the parent organisms. Asexual reproduction is called asexual reproduction because the person splits into two people that have the same genes, as opposed to sexual reproduction.
2. TRUE OR FALSE: Most members of a species show differences, or
variations.
O true
O False
Answer:
True.
Explanation:
There is a thing called bio-diversity, which means that even though siblings might be the same gender, they won't look exactly the same. Same with animals. Some animals might be bigger, faster, stronger, or smarter than others from the same species.
Imagine that an area was set aside to relocate orangutans displaced from their rainforest habitats. A solution like this would involve many groups of people and careful considerations. Review the questions below, then develop at least two additional questions that could be considered.
What do orangutans use for shelter in their native ecosystem?
How much area does a specific number of orangutans need?
Answer:
a) Orangutan prefer to shelter in leafy trees or only leaves
b) One territory is of size 9 sq. km.
Explanation:
a) Orangutans spend a large part of their life in tropical rainforest trees. They prefer to sleep on the bunch of green trees and protect themselves from harmful weather conditions by using broad leaves of rainforest trees.
b) Each individual territory of a male Orangutan is near about 9 sq. km. and can extend up to 15 square kilometer. In one territory only one male lives along with other females and young ones.

study the punnett square below. what percentage of the offspring are heterozygous
Answer:
50%
Explanation:
Heterozygous is when both of the alleles are different. Since AA and aa are the same allele, the other two Aa and Aa have on capital and one lowercse and for that reason they are different and thus heterozygous. Since 2.4 are heterozygous, 50% is the answer.

Answer:
Explanation:
1 kJ = 1000joules
15kj = 15000 joules
1 Megajoules = 1000000 Joules
3.5 mj = 3,500,000 joules
1kj = 1000joules

A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.
- Cyanide is a strong cytochrome c oxidase inhibitor. Cytochrome c is the last enzyme in the
electron transport chain. If cell is exposed to cyanide, most of the cyanide will be found in which
of the organelles?
Cyanide binds to Fe3+ in heme-containing proteins. This inhibits the terminal cytochrome complex IV of the electron transport chain. The blocklock of complex IV by cyanide depletes ATP culminating in cell death. Oxygen is unable to reoxidize the reduced cytochrome a3. Thus, cellular respiration is inhibited, as well as ATP production, in essence depriving the cells, tissue, and, ultimately, the whole body of oxygen. Hypoxia evolves into metabolic acidosis and decreased oxygen saturation. The extent of lactic acidosis indicates the severity of the cyanide poisoning. In a collapsed individual, plasma lactate is an indicator of cyanide poisoning. In severe cyanide poisonings, up to 98% of the cyanide in the bloodstream is tightly bound to red blood cells. The ancillary response is myocardial depression and decline in cardiac output. Bradycardia, hypotension, and cardiac arrhythmia then develop into VF and cardiovascular collapse.

write two examples of consumers tell whether they are herbivores omnivores carnivors or scavengers
Answers
Lion,Tiger -Carnivores
vulture- scavenger
Cow,sheep -Herbivores
Man, Pig -Omnivores
In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.
Consumers can be classified into several categories based on what they eat. For example:
Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

Answer:
Several billion years after its life starts, a star will die. How the star dies, however, depends on what type of star it is. Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. However, some hydrogen fusion will occur in the upper layers. As the core contracts, it heats up.
