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.

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

Answers

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).

1. explain how body plan and anatomy enables invertebrate to perform essential functions it needs to survive.

2. explain how body plan and anatomy enables chordate to perform essential functions it needs to survive.

3. explain how body plan and anatomy enables primate to perform essential functions it needs to survive.

Answers

Answer:

1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:

-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.

-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.

-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.  

-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.

2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.  

Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail  

This is us, we have thumbs, and vertebrates.

3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera

Explanation:

A. Write two sentences explaining how carbon returns from the air to the ground. ​

Answers

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.

A panda (herbivore) eats bamboo shoots and leaves, while a lion (carnivore) preys on other animals.A bear (omnivore) eats both plants and animals, while a vulture (scavenger) feeds on the remains of dead animals.What are consumers?

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.

- 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?​

Answers

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.
