Answer:
By covering the solution.
Explanation:
The anaerobic condition is maintained to ensure that the fermentation process is completed by covering the solution so that no oxygen enters the solution. Anaerobic conditions are necessary for the fermentation process because the anaerobic conditions allow the production of lactic acid, ethanol and carbondioxide gas from pyruvate. Without anaerobic condition, the fermentation process does not occur so that's why we can say that anaerobic conditions should be maintained for the fermentation process.

The statement which is not true about genetic disorders is that genetic disorders are curable.
What are genetic disorders ?A genetic disorder is a disease that is caused by a change, or mutation, in an individual's DNA sequence.
Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured. However, approaches may be available to treat or manage some of the associated signs and symptoms.

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.

Answer:
It's aquifier.
Explanation:
Precipitation is at the top because it any form of water that falls from clouds and reaches Earth's surface. It is not aquitard because that is a slab of impervious surface at the bottom of an aquifer that does not allow water to go through and is at the bottom of the image. The arrow is the gravity, so the only thing left is aquifier, a permeable layer of rock and sediment that stores and brings groundwater in enough quantities to supply wells.

Answer:
the Frequency remains constant
Answer: So if a wave slows down, its wavelength will decrease. ... Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

Answer:
Dear Mr. President,
Your strong voice has called attention to the risks of human-induced climate change and the need to take timely and effective steps to address it. We are pleased to report further progress in our efforts to advise you on climate policy options that could help encourage these steps.

Mr. President, our temperatures are consistently rising while moisture is increasingly evaporating. Forest management is merely one piece of the puzzle — something our own firefighters would be quick to remind you. Since 2009, our state has spent more than $130 million on forest health and fire preparedness. These events still overwhelm our residents and resources, because these fires are unlike anything people have seen before.

The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of a Choose... pattern. This pattern includes Choose... extinction, which tends not to disturb ecosystems, as well as Choose... extinction, in which ecosystems change drastically.
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.

A galaxy can be defined as a collection (group) of many billions of stars, that are existing independently or by themselves.
Generally, the greatest or largest number of stars are found in a galaxy.
However, it is only a small fraction of the universe's galaxies that can be seen from planet Earth, even though it contains many billions of stars.
The stars, galaxies and planets which can be seen which can be seen from planet Earth makes only 4 percent of the universe according to space researchers, referred to as astronomers.
In conclusion, the proportion of the universe's galaxies which can be seen from planet Earth is approximately 10 percent.

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??
