Explanation:
A major freeway runs along a stretch of the ocean shore. Over time, scientists begin to
notice a decrease in the number of intertidal organisms. Which of the following is the most
likely cause of the problem?
O A. toxic waste spilled during accidents on the
road
B. runoff of oil and other chemicals from the
road
C. wastewater from the city across the
freeway
O D. Any or all of the above could be causing
the problem.
Answer:
D. Any or all of the above could be causing the problem.
Explanation:
Pollution has been said to have adverse effect on living organisms. In this question, a decrease in number of intertidal organisms has been observed. Since a major freeway runs along a stretch of the ocean shore, the most likely cause of the death of the intertidal organisms is the release of any form of toxic waste into the water body.
Oil pollutants causes death of living organisms by hindering the entrance of oxygen into the water body. It makes it difficult for oxygen, which is a requirement for life, to penetrate the water body. Hence, living organisms in the water body will suffocate and die.
Toxic wastes also causes the death of organisms when ingested in excess. Waste water causes deterioration in the oxygen content of the water body. Hence, any or all of the above options can likely cause the reduction in number of the intertidal organisms.

Which of the following best compares viral reproduction to reproduction in other organisms?
A. Viruses do not contain genes that are replicated and passed on.
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce.
C. Viruses and single-celled organisms use mitosis as a reproductive process.
D. Viruses can only reproduce asexually while other organisms have a choice.
Answer:
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce
Explanation:
Virus is an organism that is incapable of replicating on its own without infecting a living host cell. A viral cell is dependent on a living host to replicate and express its genes. Hence, the infection cycle of a virus is its reproductive life cycle.
Other living organisms e.g plant, bacteria, fungi etc. have the ability to reproduce i.e. multiply on their own through asexual or sexual means. However, on the contrary, a virus must infect a living host, hijack the replicational abilities of the host cell in order to reproduce. Based on this, a virus employs a lysogenic or lytic cycle or both on its host to reproduce.
What are two possible ways in which mining metals affects the environment
Explanation:
environmental environmental impacts of mining can occur at local, regional,and global scales through direct and indirect mining practices. impacts impacts can result in erosion, 5 roses, loss of biodiversity, order contamination of soil, groundwater groundwater,and surface water by the chemical limited from mining process. Europethese processes also have an impact on the atmosphere from the emissions of carbon dioxide which have effect on the quality of human health and biodiversity.

Answer: B) Hearing
Explanation: Hearing, equilibrium detection, skin tactile perception, deep tissue perception, and arterial pressure perception are all supported by mechanoreceptors. Mechanoreceptors in the inner ear are involved in the conversion of sound waves into neural signals during hearing or audition.
how are layers that form ice similar to tree rings
Answer:
each new layer or ring represents a year of growth, depending on its thickness, you can tell if it had good growth or not so good growth.
They can both tell you things about the past climate changes.The tree rings represents each year and the ice sheets represents the past climate conditions.
A blastocyst is a group of cells that forms after a human egg is fertilized. The
blastocyst consists of two types of cells. Some of these cells will become the
placenta. What do the other cells develop into?
A. All of the cells of a developing fetus
O
B. The skeletal and muscular systems of the fetus
a
C. The umbilical cord linking the fetus and mother
O
D. The nervous and endocrine systems of the fetus
SUBV
Answer:
A. All of the cells of a developing fetus
Explanation:
As stated in the question, the blastocyst is a collection of cells formed as a result of several divisions of the ZYGOTE. This means that the zygote at some point becomes a blastocyst. The blastocyst itself is a collection of cells that make up the inner and outer layer. The outer layer is called trophectoderm, which gives rise to the trophoblast that later develops into the PLACENTA that nourishes the embryo.
The cells that make up the inner layer forms the embryo. These cells are stem cells that will eventually differentiate into all the cell types that makes up an embryo.

What happens to electrons when pigments in Photosystem II absorb light? They become excited and break down the pigments to release ATP. They are pumped across the membrane into the thylakoid. They move through an electron transport chain to Photosystem I. They combine with oxygen and hydrogen to produce water.
Answer:
They move through an electron transport chain to Photosystem I.
Explanation:
High-energy electrons move through the electron transport chain from photosystem II to photosystem I. Energy from the electrons is used by the molecules in the electron transport chain to transport H+ ions from the stroma into the inner thylakoid.
Answer: They move through an elctron...
When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. The high-energy electron is passed to an acceptor molecule and replaced with an electron from water.
Explanation:
A physician wants to observe the monocytes from a patient. Design an experiment the physician can perform to retrieve monocyte cells.
Answer:
White blood cells can be called the strong defender of our body from foreign substances. These cells are responsible for increasing the immunity power of a person.
Explanation:
Monocytes cells are also called white blood cells. These cells play a role an antigen that fight with outer danger and protect other white blood cells as well and prepare other cells to reduce the dead blood cells and renovate new blood cells.
These cells prevent cancer cells and fight against foreign antigens or particles. The Monocytes are the cells that develop in the bone marrow of a person and develop red blood cells.
In white blood cells, some macrophages cells are called the scavengers in the bone marrow that eat foreign particles and increase the immunity power of the person. The diagnose can be done with the help of blood testing.
