Answer #1: The Savanna biome has had a lot of human impacts affect the environment and health of the Savanna. The African people use the Savanna land not just to live on but to graze their cattle and goats. The grasses get completely eaten and with no vegetation, the Savanna turns into a desert.

Answer #2: Humans have affected the savanna biome in many ways.  The increased use of the savanna by humans has caused degradation of this biome.  Extinction of animals in this biome is caused by humans releasing foreign species into the savanna.  Humans have killed predators, built dwellings, and cleared land to be able to farm.  Humans have done things like stopping natural fires and starting fires in this environment which kill many plants and animals if they get out of hand.

The phenomenon in which when Bаlаnus аnd Chthаmаlus occur together, Chthаmаlus аdults аre found only in the more stressful upper portions of the habitat where they are more prone to desiccation is an example of competitive exclusion reducing the size of Chthamalus' fundamental niche to a smaller realized niche.

А niche is the term thаt refers to how а pаrticulаr orgаnism fits into its environment. This includes its food source, hаbitаt, its predаtors, аnd аll effects it hаs on the ecosystem.

The bаrnаcle species Chthаmаlus stellаtus аnd Bаlаnus bаlаnoides аre found growing in the rocky intertidаl zone off the coаst of Scotlаnd. Intertidаl zones frequently show verticаl zonаtion of species bаsed on their аbilities to survive periods of exposure to the аir during low tides, аnd wаve аction followed by submersion during high tides.

Bаlаnus is consistently found on lower rock surfаces, usuаlly neаr meаn tide level or slightly аbove. Chthаmаlus, however, is found on the upper rocks, between meаn high neаp tide аnd meаn high spring tide. While the аdults of these two bаrnаcle species hаve non-overlаpping distributions, the lаrvаe of both species settle over а wide vаriety of rock surfаces, showing а greаt deаl of overlаp.

In a mature human testis, spermatogonia, spermatocytes, spermatids, and sperms should be formed in the proper order during the spermatogenetic process.

Spermatogenesis is the cycle by which haploid spermatozoa are formed. They develop from germ cells. These germ cells develop in the seminiferous tubules of the testis. This cycle begins with the mitotic division of immature microorganisms near the cell layer of the tubules. Thus the primary spermatocyte divides into two haploid daughter cells called secondary spermatocytes. Each secondary spermatocyte now undergoes a second. Each secondary spermatocyte now undergoes a second maturational division that is mitotic. Thus each secondary spermatocyte gives rise to two spermatids that are transformed to form two spermatozoa.

Adding compost to farmed soil is better than adding synthetic fertilizers for a variety of reasons. Perhaps the most important of these is that compost contains disease fighting microorganisms that synthetic fertilizers lack.

These microorganisms help to keep the soil healthy and reduce the chances of plant diseases. The microorganisms in synthetic fertilizers, on the other hand, can sometimes spread plant diseases.

Another advantage of adding compost to farmed soil is that it contains carbon. Over time, the use of only synthetic fertilizers can lead to a loss of soil carbon content, which is essential for healthy soil. In contrast, compost adds carbon and helps maintain the soil’s fertility.

Finally, it’s important to consider the environmental impact of synthetic fertilizers. Synthetic fertilizers are adding the primary chemicals to the atmosphere that contribute to the ozone hole. In contrast, compost is a natural product and does not contribute to environmental pollution.

In one sense, the term “genotype”—like the term “genome”—refers to the entire set of genes in the cells of an organism. In a narrower sense, however, it can refer to different alleles, or variant forms of a gene, for particular traits, or characteristics.

Based only on a pedigree, you might not always be able to ascertain the genotype of a person. An person may occasionally have homozygous dominant or heterozygous alleles for a characteristic. The relationships between a person and their parents, siblings, and children are frequently used to identify genotypes. The phenotypes of the children can be used to identify the unknown genotype. The unknown individual is homozygous dominant if pairing the recessive phenotypic individual with the unknown dominant phenotype (PP or Pp genotype) results in only dominant phenotypes (no recessive).

Physical and chemical qualities are present in all matter.

Physical qualities, such as mass, color, and volume, are characteristics that may be measured by scientists without modifying the makeup of the sample being studied (the amount of space occupied by a sample). Chemical characteristics define a substance's distinctive capacity to reacted to produce new chemicals

A substance's physical qualities is a quality that can be seen or quantified without affecting the substance's identity. Shiny silver is a metal with excellent electrical conductivity. The ability to be molded into thin sheets is known as malleability. Salt is brittle and dull, but when it dissolves in water, which it does rather easily, it conducts electricity. Color, hardness, malleability, solubility, electrical conductivity, density, melting point, and boiling point are examples of the physical characteristics of matter.

The hue of the elements does not differ much from one element to the next. Most elements are either colorless, silvery, or gray. Sulfur and chlorine are both yellow in color, copper is (obviously) copper-colored, while elemental bromine is red.

The neuroanatomic substrate that directs the process of decision on whether or not to go ahead with the action of brain reward is Septum.

As a component of the basal forebrain, the medial septum (MS) supports a variety of physiological processes, including sensorimotor integration and cognition. The MS coordinates oscillatory neuronal processes across the entire brain by frequently reciprocal connections with a wide variety of peers across all main divisions of the brain. These oscillations are essential for creating sensory and emotional salience, regulating learning and memory, maintaining mood, sustaining intrinsic anxiety, and supporting locomotion.

A growing body of research shows that diseased situations regularly interrupt or change the physiological oscillations that are influenced by the septum. In order to restore normal patterns or eliminate undesirable ones, it may be possible to treat neurological and mental illnesses with aberrant oscillations (oscillopathies) by targeting the MS. Recent research has shown that the patterned stimulation of the MS reduces epileptic symptoms.

a). The trp repressor protein is inactive, thus that is the right response. b). The promoter can be bound by RNA polymerase,

A trp operon is a collection of genes that code for the enzymes needed to synthesize the amino acid tryptophan. When tryptophan is present in low concentrations, the trp operon is active; conversely, when tryptophan is present, the trp operon is inactive. This is because it is a repressor protein and attenuation (coupled transcription and translation) controlled mechanism.

When tryptophan is present, the repressor binds to the operator of the DNA sequence, blocking the RNA polymerase's path and ending transcription. When tryptophan is absent, the repressor molecule is inactive and RNA polymerase can promote the transcription of genes after binding to the promoter sequence. Therefore, the right response is "inactive and promoter."
