B
Explanation:
When the producer gets its energy from the sun and gets eaten, less energy passes on. This cycle continues as it goes one consumer up the ecosystem pyramid until it reaches the highest level.
Which of the following best explains the connection between increased competition and the evolution of a species by natural selection?(1 point)
(A) Individuals that must compete for limited resources are more likely to have diseases that cause mutations.
(B) Individuals that have traits that allow them to outcompete others survive better and produce more offspring.
(C) Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation.
(D) Individuals migrate to another area in order to avoid competition for limited resources in the current ecosystem.
Answer:
B.
Explanation:
For A, more limited resources doesn’t mean more to mutations, mutations are random. C is incorrect, D and doesn’t explain the connection.
Natural selection occurs in individuals that have traits that allow them to outcompete others survive better and produce more offspring.
What is natural selection?Natural selection is the process by which organisms are selected for survival in their environment by natural processes which depends on the ability of the organism to adapt to their environment.
These traits enable the organism to adapt to changes in their environment.
Therefore, natural selection occurs in individuals that have traits that allow them to outcompete others survive better and produce more offspring.

Answer:
the nervous system sends instructions to the body about how to respond to stimuli
Explanation:
Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.

Explain Genes in a expert way i will give bfrainlest who has the best answer
Answer:
Genes are pieces of DNA (deoxyribonucleic acid) inside each cell that tell the cell what to do and when to grow and divide. Each gene is made up of a specific DNA sequence that contains the code (the instructions) to make a certain protein, each of which has a specific job or function in the body. Each human cell has about 25,000 genes.

A mutation in a gene results in an animal that cannot make a protein that
allows muscles to contract. Which of these is most likely to happen? *
A. The gene will eventually be found in all animals of the species.
B.The animal will die before having any offspring.
C.The gene will change back to the normal form.
D.The animal will pass this gene on to many offspring.
The effect of a mutation in a gene results in an animal that cannot make a protein that allows muscles to contract is that the animal will die before having any offspring.
What is mutation?Mutation is any change in the nucleotide sequence of the DNA.
Since genes are responsible for the synthesis of proteins, this means that a change in the nucleotide sequence of the gene will affect the production of proteins.
According to this question, a mutation in a gene results in an animal that cannot make a protein that allows muscles to contract.
This means that the animal will die before it gets the chance to produce offsprings.

What is a quantum number
Answer :
Quantum numbers are used in chemistry and quantum physics to explain the values of conserved quantities in the dynamics of a quantum system.
Quantum Number of Angular Momentum (l)
The angular momentum quantum number (l) denotes the general shape or area in which an electron exists—its orbital shape. The value of l is determined by the value of n, the fundamental quantum number. Positive values of the angular momentum quantum number range from zero to (n 1).

where does natural selection happen ?
Answer:Natural selection occurs in nature obviously. There are quite a few reasons natural selection happens. One of the reasons natural selection occurs is because sometimes more offspring are born but not all of them survive.

In 1993 , geochemist Michael Russell proposed a mechanism by which life could have started on Earth as long ago as 3.5 billion years He proposed that life came from harnessing the energy from gradients that form when extremely alkaline water mixes with more acidic seawater . This proposal BEST describes which origin of life theory ?
Answer:
Hydrothermal vents
Explanation:
At the time of life's origin, the early ocean was acidic and filled with positively charged protons, while the deep-sea vents spewed out bitter alkaline fluid, which is rich in negatively charged hydroxide ions.

The unicellular spores of the fern Ceratopteris richardii are about 100 μm in diameter. Calculate the surface-area-to-volume ratio of a cube whose sides are 100 μm in length to approximate the surface-area-to-volume ratio of the fern spore cell. Show your work.
Answer:
Take 6(100x10^-6)^2 which is the surface area of it.
The volume is (100 x 10^-6)^3 this is the volume of it.
This is the surface to volume ratio, so 6(100x10^-6)^2 divided by (100 x 10^-6)^3.
Moreover the volume is 6 x 10^4

state when this reaction occurs (fibrinogen)?
Answer:
Thrombin, in turn, catalyzes the conversion of fibrinogen (factor I)—a soluble plasma protein - into long, sticky threads of insoluble fibrin (factor Ia). Blood-clotting proteins generate thrombin, an enzyme that converts fibrinogen to fibrin, and a reaction that leads to the formation of a fibrin clot.

(c) If the Wakame culture is maintained for an additional 120 days, predict the most likely effect on
the number of cells counted every five days. Provide reasoning to justify your prediction. (2 points)
The most likely effect this will have on the number of cells counted every five days is ;
There will be a decline in the number of cells ( Wakame )Incubation periodAs the incubation period increases the number of cells will start declining as the stationary phase has already been achieved between 25 to 30 days. also as the nutrient in the medium decreases the cells will try to adapt the the starvation which will lead to the decline in the number of cells.
Hence we can conclude that The most likely effect this will have on the number of cells counted every five days is ; there will be a decline in the number of cells ( chlorella )

Explanation:
Because the decay is close to the pulp chamber, the tooth must be monitored for the next few weeks to determine the health and extent of decay of the affected tooth. The dental assistant will need to set up for an intermediate restoration that will consist of the IRM material.
The pulp chamber of the tooth is the inner area of the tooth that houses its pulp. If the tooth enamel is compromised, as in a cavity, bacteria can enter the chamber and affect the dental pulp.
What is IRM in Dentistry?IRM is a temporary filling cement. Restorative material based on Zinc Oxide and Eugenol. Indication: Long-term temporary filling (up to one year). Great compressive strength.
With this information, we can conclude that the pulp chamber of the tooth is the internal area of the tooth that houses its pulp. If the tooth enamel is compromised, as in a cavity, bacteria can enter the chamber and affect the dental pulp.
