This type of inetraction between organisms called intraspecific completetion.
Intraspecific competition is competition between individuals of the same species (interspecies). The impact of competition on each individual within a species depends on the type of competition taking place. "Competition-competition" can be passive or active, with different results.
For example, two male birds of the same species may compete for mates at the same location. This type of competition is a fundamental element of natural selection. It leads to the development of better adaptations within the species.
A species is a group of organisms made up of similar individuals whose genes can be exchanged or interbred. Species is the primary natural taxonomic unit, ranked under the genus and represented by the Latin binomial.

What is the correct sequence of events for activation of a b cell by a t-dependent antigen?.
The correct sequence of events for activation of B-cells by T-dependent antigen is recognition of antigen, fragmentation, binding and secretion.
The process can be understood as firstly immunoglobulin receptors on the B cell recognize and bind with the antigen, secondly an antigen fragment in complex with MHC class 2 is displayed on the B cell's surface, thirdly the MHC-antigen complex binds a receptor on a TH cell and finally the TH cell secretes cytokines that activate the B cell. B-cells are the antibody producing cells that produce antigen specific immunoglobin molecule to fight against the pathogens such as bacteria or fungi. These B-cells are found in bone marrow of an individual. Lesser number of B-cells in the body makes it prone to infections as the immune system gets weak. T cells are the types of white blood cells primarily involved in directly killing of infected host cells, activating other immune cells, producing cytokines and regulating the immune response.

Why are parasite numbers pyramids often inverted, with the bottom level smallest?.
One producer might have a lot of parasites; thus, parasite numbers of pyramids are sometimes inverted, with the bottom level being the smallest.
In parasitic food chains, a number pyramid is discovered to be inverted. In these food chains, a single producer typically supports a large number of parasites. More hyper-parasites are supported by the parasites in turn. In this pyramid, the number of people at each level rises from the lowest to the highest.
A graphical representation of the number of creatures at each trophic level is a pyramid of numbers. Given that producers are always more numerous than other trophic levels in an ecosystem, it is a vertical pyramid. There must always be enough plants at the bottom to create food, hence the pyramidal design. If not, the entire food chain would be destroyed. No predator can be as common as its victim at the upper level.

Which species concept is primarily used to define extinct species known only from the fossil record?.
Phylogenetic species concept is primarily used to define extinct species known only from the fossil record.
What is Phylogenetic species?Although species serve a variety of special and essential functions in biology, none are more crucial than their involvement in phylogeny, naming, and biodiversity research. There is no way to divide species into smaller units where shared derived features may be accurately identified. A universally applicable species idea is necessary for biodiversity inventory, evaluation, and conservation. In formal Linnaean classification and zoological nomenclature, species are the fundamental units.
The Biological Species Concept pushed a basic taxonomic problem—what are species?—into a population genetics framework—why are there species?—and has long had only minimal support from most zoologists. Early attempts to develop a phylogenetic species concept concentrated on fixing issues with the biological species concept related to ancestral populations before applying phylogenetic reasoning to the actual species.

list 2 electron carriers and explain the function of each when in the oxidized state and in the reduced state
Answer: Flavin Adenine Dinucleotide (FAD)
Nicotinamide Adenine Dinucleotide (NAD)
Oxidation and reduction are coupled reactions in which electrons are transferred form one atom to another atom. Reduced compounds donate oxygen or accept hydrogen and oxidized compounds accepts oxygen or donates hydrogen.
So, when the electron carriers are in reduced condition, they accept hydrogens from different metabolic pathways, like glycolysis and TCA cycle, etc. In oxidized state they enter into ETC and donate protons for ATP synthesis. For example, 1 NADH gives 2.5 ATP and 1 FADH2 gives 1.5 ATP.

If pacific field male crickets in hawaii attract females by rubbing their wings together to sing, why is it that in some places up to 90% of the males no longer sing? how could this have evolved?.
Answer:
to shield from predators
Explanation:
A certain mutation causes crickets to stop singing; and not for no reason, it happened as a result of parasitic flys that used the song to find hosts-- and although it worked and fewer crickets died from the parasite it also meant that certain crickets couldn't attract females. This evolved as a way to prevent the parasites from finding crickets and killing them but unfortunately also prevents females from finding them. I hope this helps!

What is clover?
Clover is a member of the distinguished legume family. On the roots of legumes are bacteria that can convert atmospheric nitrogen into a form that plants can use. Plants utilize nitrogen in large quantities since it is a component of chlorophyll. The farmer enriches the soil with plenty of nitrogen and organic matter by planting clover and plow it beneath. A crop would be seeded after allowing the organic matter to decompose.
Advantages of clover in agriculture:
Clover is a Fixer of Nitrogen.
Clover is a legume crop that is a member of the bean and pea plant family. It helps the soil fix nitrogen. In other words, it works with helpful bacteria to convert nitrogen gas that is present in soil air pockets into stable organic molecules that feed nearby plants.Animals Love It
Because it is so nutrient-rich, clover provides farmers with a high-protein meal for their animals and enhances digestibility. Leaner meat and more nutrient-rich milk are produced as a result of reducing mineral deficiency, which can cause a number of illnesses and problems.Additionally, clover can be used as poultry feed for chickens, geese, and birds (and even humans - clover is edible and its colorful flowers can really make a salad pop).Positive insects and pollinators I adore it, too
Honey bees are drawn to the readily available nectar found within the small florets of white clover and crimson clover, which is why clover honey isn't simply a smart name.

Controlling its metabolism is essential since it supplies the energy required for cell activity (see fermentation, gluconeogenesis). Each starch molecule, which serves as plants' primary source of energy, is composed of thousands of linear glucose units.
Another important linear molecule that is primarily composed of glucose is cellulose. Dextrose is the ingredient in D-glucose.
