arteries carry blood back to the heart and veins carry blood to the heart
Answers
The correct option is :
=》arteries do not have valves and veins do have valves.
Arteries don't have valves because back flow of blood isn't possible due to high pressure, but blood in veins doesn't have high pressure just like arteries, so to stop backflow of blood, veins have valves.

Which process occurs by osmosis?
Select one:
a. plant roots absorbing water from the soil
b. the small intestine absorbing fatty acids into the blood
c. the small intestine absorbing glucose into the blood
d. plant roots absorbing mineral ions from the soil
Answers
Because osmosis involve water.
Plant roots absorbing water from the soil occurs by osmosis.
Are roots absorbing water osmosis?Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Do plants absorb water through osmosis?Plants absorb water and minerals salt from the soil with the help of root hairs. They absorb water by the process of osmosis. Osmosis is the movement of water molecules (solvent) from a lower concentration solution to a higher concentration solution through a semi-permeable membrane.

c.
viruses originate from bacteria cells
d.
viruses don't evolve
Answers
Answer:
b.
viruses may have been the first self-replicating entities
Explanation:
The “virus-first” hypothesis states that viruses predated cells and contributed to the rise of cellular life. A significant proportion of all the viral genomes encode for genetic sequences that lack clear cellular homologs. Presence of such virus-specific sequences provides support to their unique origin.

What is the most important influence of the forest ecosystem on the environment
Answers
Answer:
Forests
Explanation:
Forests have also sanitary influences upon environment due to the production of oxygen through photosynthesis.
The study of the environment is called ecology. There are two types of factors for an ecosystem and these are a biotic and abiotic factors.
The correct answer is light
What is photosynthesis?The process of the formation of food by trapping the sunlight with the help of chloroplast is called photosynthesis.
According to the question, the most influential factor which affects the environment is light as all the plants directly depend on the light for the formation of food and all the other species are dependent on plants either directly or indirectly.
Hence, the correct answer is light.

5. In 1928, Alexander Fleming noticed that a mysterious blue-green fungus had grown on some bacterial colonies that were known to cause strep throat. Upon closer inspection, he noticed that the bacterial colonies did not survive when introduced to the fungus. He questioned if something in the fungus stopped the bacteria from growing. Which steps in the scientific method are included in this story
Answers
Answer:
The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.
Explanation:
The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.
In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.

Answer:
Hi your answers would be transcription factors, TATA boxes, and homeotic genes
Eukaryotic gene regulation takes place through the use of RNA- binding proteins called transcription factors and short regions of DNA that help position RNA polymerase called TATA boxes.
At the organism level, homeotic genes control the differentiation and development of cells during embryonic development.
Transcription factor:Transcription factors are proteins involved in the process of converting, or transcribing, DNA into RNA. Transcription factors include a wide number of proteins, excluding RNA polymerase, that initiate and regulate the transcription of genes. Regulation of transcription is the most common form of gene control.
