Most animal and plant species we see in the fossil record are extinct, or no longer living. In fact, of all the species that ever lived, 98% are extinct. Animals and plants become extinct over time as a result of natural processes. Their habitat might change or a disease might wipe out a species.

The trend of extinction and difference in body parts in the complexity of life

over time is seen through the fossil record

Fossils refers to remains of living organisms which have been replaced in the form of rock particles due to its presence in the soil for a long period of time.

The fossils contain an understanding of the structures and characteristics

the animals had which is then compared to its present structures. This helps

to explain how the animals adapted to climate change through changes in

the structure, shape of parts of the body.

It also tells the location of animals and their different movements in response to challenges faced in the ecosystem.

The Malthus predict about the human population as it would grow until it had to compete for food. Therefore, option (D) is correct.

The total number of people alive today is referred to as the world population. In the middle of November 2022, the United Nations estimated that it had reached more than eight billion.

There are 4 primary qualities of the populace structure: age, orientation, nationality, and thickness. The population structure is influenced by three main factors: Migration, mortality, and the birth rate.

Understanding how populace attributes, for example, size, spatial dissemination, age structure, or the birth and demise rates change over the long haul can assist researchers or legislatures with simply deciding.

Answer:  Here's what I could find:

Ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs. An mRNA travels to the ribosome and uses information it contains to build a proteins with specific amino acid sequences.

Explanation: I'm pretty sure it's protein, if not then it's DNA.

Answer: steel nickel

Explanation:

They receive their order for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA, which is also called (mRNA). mRNA travels to the ribosomes, which translate the code provided by the sequence of the nitrogenous bases in the mRNA into a specific order of amino acids in a protein.

The location of fossils in rock layers provides evidence of Earth's past landscapes. It is hard to guess the age of rock. Scientists have to act like detectives, piecing together a mystery to determine how long ago rocks formed. Fossils found in a particular rock layer help scientists determine the age of the rock.

Hope this helps you, may i have brainliest please.

What we cannot learn from the fossils found in rock strata is: the diversity of organisms at a certain location or during a certain time period.

Rock strata (layers) that are found in various parts of the world are usually different from one another because they all comprises distinct Earth's geological history, which are referred to as fossils.

A fossil can be defined as the mineral impression or remains of both living and non-living organisms that are prehistoric in nature.

This ultimately implies that, fossils are ancient organisms such as plants and animals that were formed into rocks.

Answer:

Digestive enzymes speedup reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive.

Explanation:

Explanation:

In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.

Answer:

See the answer below

Explanation:

Yes, the cells in one human contain the same DNA. However, during gene expression, not all the genes are expressed for every cell. Only a specific region of the DNA is expressed in cells and the cells in which the same DNA region is expressed end up performing similar roles in the body of organisms. The portion of the DNA that is expressed dictates the function which these cells will serve. This is called the differentiation of cells.

Cell specialization and tissue differentiation are due to the fact that although somatic cells have the same DNA, they express different genes and therefore generate different cells/tissues.

The human body contains approximately 200 cell types, which can be classified into four types of tissues: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

All these tissues and cell types are derived from three embryo layers, i.e., ectoderm, mesoderm, and endoderm.

The process of differential gene expression from these three embryo layers leads to the development of different types of cells/tissues in different regions of the developing embryo.

For example, the expression of the connective tissue growth factor (CTGF) gene has been associated with the generation of connective tissue during embryo development.

In conclusion, cell specialization and tissue differentiation are due to the fact that although somatic cells have the same DNA, they express different genes and therefore generate different cells/tissues.

How do algae blooms destroy aquatic life?

by giving off toxins that kill life

A harmful algal bloom (HAB) contains organisms (usually algae, hence the name) that can severely lower oxygen levels in natural waters, killing marine life.

What, besides temperature can make ocean water significantly denser

salinity

High salinity makes water denser. This is because there is more salt packed into the water. High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense.

Which area best describes a continental slope?

Continental slopes are regions of steeply sloping seafloor that lie between continental shelves and the deep ocean basins (Figure 2). Regional gradients are typically 2–5°, but locally slopes may be much steeper.

Algae blooms destroy aquatic life because of the decomposition of algae depletes oxygen needed by organisms.

When algae and bacteria in an algal bloom die, the decomposition process consumes the surrounding oxygen which leads no presence of oxygen in the water body and the aquatic organisms die because of suffocation.

So we can conclude that Algae blooms destroy aquatic life because of the decomposition of algae depletes oxygen needed by organisms.

Answer:

a food web

Explanation:

What they saw was a food web, which refers to connections of food chains showing how energy and nutrients are transferred from one organism to the other.

In this example, we observe there are seven organisms (fish, algae, snails, insects, frogs, raccoons + bacteria contained in the pond) in focus here.

The green algae are Producers (because it produces its own food, not dependant on others)

The bacteria act as Decomposers. ( because they process organic waste into meaningful natural nutrients again)

The other organisms are Consumers. (because they are dependant on others for their nutrition).
