Answer:
macroevolutionary; background; mass
Explanation:
Macroevolution is defined as the evolutionary process of higher taxa (above the species level). Macroevolutionary patterns include stasis (lack of evolutionary change over a long period), speciation (diversification), lineage character change (modification of major features/traits), and extinction (termination of a species or taxon). Moreover, background extinction refers to the extinction of individual taxon/species due to environmental factors (e.g., climate change, disease, habitat loss, competition, etc), which account for the majority of all extinctions. Conversely, mass extinction refers to the time period in which a major proportion of all known species (about three-quarters or even more of all species) living at the time goes extinct.
can someone please help me with these
Answer: 1. Also known as stolons, runners are modified stems that, unlike rhizomes, grow from existing stems just below the soil surface. As they are propagated, the buds on the modified stems produce roots and stems. Those buds are more separated than the ones found on the rhizome. 2. Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. ... The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell. 3. the population can increase rapidly when the conditions are favourable.
only one parent is needed.
it is more time and energy efficient as you don't need a mate.
it is faster than sexual reproduction. Organisms do not need to find a partner, this saves time and energy. Because the offspring inherit a unique combination of genetic information they are all different. 4. In mitosis, motor proteins carry chromosomes or other microtubules as they walk. Telophase. The spindle disappears, a nuclear membrane re-forms around each set of chromosomes, and a nucleolus reappears in each new nucleus. The chromosomes also start to decondense. Mitosis is the process in which the nucleus of a eukaryotic cell divides. During this process, sister chromatids separate from each other and move to opposite poles of the cell. This happens in four phases, called prophase, metaphase, anaphase, and telophase. 5. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. 6. Organisms can repair some of their tissues, using mitosis to regenerate new cells. Damaged skin, for example, constantly repairs itself through the production of new skin cells or scar tissue. Some organisms can even use mitosis to regenerate entire body parts. brainliest??

Describe the changes that occurred during the evolution of dogs from wolves?
Answer:
The dog, Canis familiaris, is a direct descendent of the gray wolf, Canis lupus: In other words, dogs as we know them are domesticated wolves. ... Not only their behavior changed; domestic dogs are different in form from wolves, mainly smaller and with shorter muzzles and smaller teeth.
Explanation:
hope this helps
Dogs were most likely domesticated by chance when wolves began following ancient hunter-gatherers to eat their garbage. The theory goes that docile wolves were given extra food scraps to help them survive and pass on their genes.
What is evolution?The gradual change in the genetic composition of the organism that led to the generation of new characters in the next generations is called evolution.
Dogs may have become domesticated because the forefathers had too much meat to eat. During the ice age, hunters and gatherers may have shared their surplus with wolves, who became their pets.
All dogs are descended from wolves, according to their ancestors. Gray wolves and dogs diverged about 15,000 to 40,000 years ago from an extinct wolf species.
Thus, it can be concluded that many changes occurred during the evolution of dogs from wolves.

What is natural selection? Describe the peppered moths example of natural selection. NO LINKS PLEASE
Natural selection is the mechanism by which beneficial alleles rise in frequency in the population over time.
The peppered moth is an example of natural selection acting to change the frequency of a certain trait in the population over time. During the Industrial Revolution, there was a directional change in the color of the peppered moth population around Manchester. That is, there was an increase in the frequency of dark colored peppered moths within the population. This was because the increased air pollution due to the industrial revolution created a situation where the dark colored version of the peppered moths had a higher relative fitness than the light colored peppered moths (which were the traditional variety). After pollution was reduced later on, there was a increase in frequency of light colored moths, as the dark colored moths no longer received a relative fitness benefit from their dark coloration.

The heart works as
A. One pump
B. Two pumps
Answer: Hello, There! your Answer is Below
B. Two pumps
Explanation:
Your heart is divided into two separate pumping systems, the right side and the left side. The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide.
Hope this helps you!!
Have a great day!!!
The heart works as two pumps.The right pump moves blood from the heart to the lungs to pick up oxygen and release carbon dioxide, then back to the heart. The left pump moves blood around the body.

In two or more complete sentences, describe a scenario where human activities are related to an increase or decrease in blodiversity in an ecosystem. Write your answer in the essay box below
Answer:
Deforestation and loss of green areas so that factories can use those areas for their benefit, exploiting the natural resources around them decrease an ecosystem's biodiversity. The invasion of industrial areas and excessive use of their natural resources causes a disbalance in the ecosystem because the plants, water, nutrients, minerals, amongst other elements, are used by industries killing animals and species, reducing populations due to pollution, and lack of food.
Explanation:
An ecosystem is a system where animals and living organisms, such as plants or bacteria, live together with nonliving elements. Living organisms interact with each other and with nonliving ones to keep the system balanced.
We can define biodiversity as the variety of living things that exist in an ecosystem.
Human activities like deforestation and the building of big factories near areas with large amounts of natural resources lead to the killing of many species. As industries kill in excess species, or they pollute an ecosystem's soil and water, the species' population decreases. Asa result, there is a disbalance in the ecosystem.
A human activity that increases biodiversity is the protection of endangered animals or laws to protect natural areas where there are many species of plants and animals that are of high importance for the planet.
