How do you think we could solve the problem of plastic pollution in our oceans?
Answer:
Starting from your own home is the best way to reduce plastic pollution. You can reduce it by stop using plastic bags, water bottles, anything that is plastic. You can reuse things instead. Use less energy. Turn off the lights whenever you leave the house or if you aren't using it. Lastly, conserve water. Don't let the water running if you aren't using it.
Hope this helps! :)

A gene, but not DNA, is passed on to the next generation.
Each chromosome contains a single gene.
Genes are located on the chromosomes.
A gene, but not a chromosome, is made of DNA.
Answer:
the only option that is correct is the third
Explanation:
the second isn’t correct because they contain strands of thousands of genes. The first isn’t correct because they are both passed on. The last one isn’t correct because they are both made up of DNA

Explanation:
what process is illustrated in the figure above?
Answer:
DNA -> RNA is transcription
RNA > Protein is translation
The process illustrated in the figure above is transcription.
What is transcription?Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.
The process of transcription starts when an enzyme called RNA polymerase (RNA pol) attaches to the template DNA strand and starts to gets catalyze the production of complementary RNA.
Large enzymes composed of a lots of dozen subunits, and when active on DNA, they are also so much complexed with other . In many cases, these signal which gene is to be transcribed.
It contains all the information within the code of amino acids and some of them also help in protein synthesis too.
Therefore, the process illustrated in the figure above is transcription.
Therefore, it is transcription.

Which word describes the scientific study of weather and the atmosphere?
meteorology
environmental science
geomorphology
atmospherology
Answer:
I think the answer should be meteorology
Meteorology is the word that describes the scientific study of weather and the atmosphere.
What is weather?Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth.
Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations.

Some types of organisms can reproduce either sexually or asexually. If environmental conditions forced a population of these organisms to use only asexual reproduction, what would be the MOST LIKELY long-term effect?
Group of answer choices
The number of chromosomes in each organism will increase.
Genetic information will no longer be transmitted from one generation to the next.
Mitosis would stop occurring in the population.
The genetic variation in the population will decrease or stay the same
Answer:
The genetic variation in the population will decrease or stay the same
Explanation:
In an ecosystem , if environmental conditions forced a population of these organisms to use only asexual reproduction, the genetic variation in the population will decrease or stay the same.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
