how do turtles interact with the abiotic factors in their environment?
Answer:
An abiotic factor that affects sea turtles is hurricanes, hurricanes affect sea turtle's nests placed on the beach, they get destroyed by hurricanes if not moved into a secure place.
Explanation:
Turtles remarkably interact with abiotic factors like water, air present in the sea, and various abnormal circumstances like floods and hurricanes.
What are Abiotic factors?Abiotic factors may be defined as those factors that significantly deal with the non-living part of an ecosystem that shapes its environment.
It includes climatic factors like temperature, light, rain, fire, winds, etc., topographic factors like mountains, hills, plains, deserts, etc., and edaphic factors like characteristics of the soil. Both biotic factors and abiotic factors are influential for the survival of living organisms.
Turtles are positively influenced by water. The nesting of turtles assists beaches by depositing their eggs in the sand. They typically get nutrients from beach grasses that help to prevent coastal erosion. The place which best suited their adaptation is excessive water present.
Therefore, abiotic factors like an aquatic ecosystem, water, winds, certain abnormal situations, etc. through which turtles interact.

A heritable change in a person's genetic makeup is referred to as a mutation. Changes can be substantial or negligible. Chromosomes or chromosome parts may be lost, added, duplicated, or rearranged in significant alterations. Thus, option B is correct.
What mutation in a gene results in an animal?High-energy sources like radiation or chemicals in the environment can both result in mutations. They may also emerge on their own during DNA replication. The two main kinds of mutations are chromosomal abnormalities and point mutations.
Mutations can alter an organism's phenotype, which is its outward appearance, or they can have an impact on the way DNA encodes the genetic information (genotype). When mutations happen, they might kill an organism completely or only partially.
The likelihood that a gene mutation will cause an animal to be unable to produce the protein necessary for muscles to contract is that the animal will perish before producing any progeny.
Therefore, The animal will die before having any offspring.

Based on the living things in the pyramid, please tell me what examples would fit into these categories:
Primary Producers, primary consumers, secondary consumers, and tertiary consumers.
Answer:
Primary producer = Oak tree leaves
Primary consumer = Caterpillars
Secondary consumer = Blue j a y s
Tertiary consumers = Hawk
Explanation:
An energy pyramid is a graph which shows how energy is transferred or flows from one trophic level to the next. Organisms which occupy the same level in the food chain within an ecosystem belong to the same trophic level.
The shape of an an energy pyramid is a pyramid indicating that the number of living things as well as the amount of energy flow decreases as one goes from one lower trophic level to the next higher level.
At the base of the pyramid are the primary producers which use energy of the sunlight to manufacture their own food. Example is the Oak tree.
The next higher level is the primary consumers who feed directly on the primary producers. For example caterpillars.
The next higher level is the secondary consumers who feed on the primary consumers. For example the Blue j a y s.
The highest levelin the pyramid is the tertiary consumers who feed on the secondary consumers. For example, the hawk.

three effects of constipation
1. Infections
If you end up being constipated, you are probably having trouble passing a stool. If the stool has become dry and hard from lack of moisture, it could make having a bowel movement painful. When the rectum is stretched out to accommodate the painful stool, the rectum could stay open resulting in rectal prolapse. This could lead to an infection.
2. Bad breath
One unusual side effect is bad breath. You may wonder how a condition that is occurring at one end of your body could affect the complete opposite end of your body, but it can. What happens is the gasses and toxic waste that are building up because you are constipated rises up and as it goes throughout the body and it usually ends up in your mouth.
3. Lowered ratio of healthy bacteria
Healthy bacteria in your body is called flora. The purpose of flora is to help with the production of vitamins and helps with your immune system. When you are constipated the amount of flora in your intestine is reduced putting you at risk for illness and infection.
Extra Options
4. Colon cancer
The colon is meant to store a couple of pounds of stools. If you become constipated, there is a buildup of stools and puts the colon at risk for ripping. When the colon becomes strained because it is overloaded, it strains the inner membrane. Ruptures and possible infections occur and it could lead to colon cancer.
5. Increased toxins
Your skin will show on the outside what your body is going through on the inside. If you become constipated, you will suffer an excess of toxins in your body. The skin, your largest organ, has to work overtime to get rid of these toxins. If your skin looks less than glowing you need to address the issues that are going on inside of your body before you start looking for a new facial cream.

A researcher studied the development of resistance to antibiotics by bacteria. She studied several antibiotics to determine how long it took for bacteria to develop resistance. She found that, on average, it took eight years for bacteria to develop resistance to an antibiotic. In some cases, bacteria developed resistance to an antibiotic within a year, and none of the antibiotics were still completely effective on bacteria after 30 years.
How is this possible?
Answer:
See Explanation
Explanation:
Antibiotic resistance is said to have occurred when a given antibiotic drug is no longer effective against the target organisms. This is as a result of genetic mutation in the organism that enable resistance to the drug.
When a drug is being used against a particular organism, the organism gradually develops genetic mutations that helps it to inactivate the antibiotic drug and increase its chances of survival. These traits are passed on to offspring, hence the onset of resistance to antibiotic drugs.
There are different mechanisms of antibiotic resistance which include; Degrading the antibiotic drugs by the use of enzymes secreted by the organism, altering proteins present in the organism upon which the antibiotic drug acts and changing membrane permeability to antibiotic drugs.

A process that selects for variations in a population that help with survival and that spreads the variations to more offspring.
3 ways in which our atmosphere is not like a greenhouse
( HELP ME PLEASE)!!!!
Answer:
1.) The atmosphere is an open system, with heat energy always escaping to space. Unlike the glass it absorbs 95% of the UV in the creation of ozone. This sounds insignificant, but one scientist argues variation in the 5 percent is the cause of warming.
2.) There are no winds in a greenhouse. In the greenhouse and in the atmosphere energy is partly transferred from the heated surfaces through collision between air molecules (conduction). However, in the atmosphere a large portion of that heat is transported vertically by rising air currents (convection), and also horizontally by advection or commonly wind. There are no winds in a greenhouse.
3.) Heat reduction in a greenhouse requires a physical change with a vent to let LW escape or a screen to block SW entering. Clouds are nature’s screen. However, they can block SW and LW, such that we have little idea how clouds work to modify temperatures
Explanation:
The basic idea of a greenhouse is that sunlight or shortwave (SW) energy passes through the glass and heats surfaces. The surfaces radiate that heat as longwave (LW) energy or sensible heat (heat you can feel). LW cannot pass through the glass, so is trapped and raises the temperature in the greenhouse; the glass acts like a one-way valve. A greenhouse is a closed system because the heat cannot escape unless artificially changed by opening vents or blocking sunlight. The glass supposedly represents the entire atmosphere. It also blocks 100 percent of the ultraviolet (UV) portion of the sunlight.
PLEASE HELP ITS URGENT What is the functionof the peripheral nervous system? A. To transmit signals between the body and the brain or spinal cord B. To transmit signals related to movement of the hands and feet C.To transport blood to the brain D. To transport oxygen and nutrients throughout the body
Answer:
The peripheral nervous system (PNS) is one of the two components of the nervous system, the other part is the central nervous system (CNS). The PNS consists of the nerves and ganglia outside the brain and spinal cord.[1] The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.[2] Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood–brain barrier, which leaves it exposed to toxins and mechanical injuries. The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve(cranial nerve II), along with the retina. The second cranial nerve is not a true peripheral nerve but a tract of the diencephalon.[3]Cranial nerve ganglia originated in the CNS. However, the remaining ten cranial nerve axons extend beyond the brain and are therefore considered part of the PNS.[4] The autonomic nervous system is an involuntary control of smooth muscle and glands. The connection between CNS and organs allows the system to be in two different functional states: sympathetic and parasympathetic
