Answer and Explanation:
Alleles are the different varieties of genes. For every gene, somatic cells have two alleles.An allele that is not expressed by an organism might be passed to the offspring of The organism provides one allele.
It is difficult to conclude which two alleles of a gene exist within the chromosomes of organisms. that organism and can express in the next generation.
The parental genotypes can be determined by PUNNETT SQUARE, in which we use two letters to signify the genotype.
As the white throat code and the red throat code are alleles.
A lowercase letter represents the recessive form of a gene (allele), and a capital letter represents the dominant form of a gene (allele). For example, for the red-throated bird, white throat is a recessive trait, and red throat is a dominant trait.
There are basic steps of using Punnett Square. Step one is to determine the parent organism genotypes then write down “mating.” Draw a p- square. For each parent, split the letters of the genotype. Then place them outside the p-square. By filling the p-square, determine the genotype of the offspring. Then summarize results.
what types of reproductive systems of female
Answer:
A female's internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries. The vagina is a muscular, hollow tube that extends from the vaginal opening to the uterus.
Once all the members of a ____ have this favorable traits then it is refferred to as an _____
Answer:
Once all the members of a population have this favorable trait, then it is referred to as an adaptation.
Explanation:
Results from multiple experiments suggest that the ActA protein of Listeria, an integral membrane protein expressed on the cell surface, is the only bacterial protein that is required for the movement of the bacterium within its host cell. Which combination of the following observations shows that ActA is both, necessary and sufficient for bacterial movement?
I. ActA binds to the Arp2/3 complex
II. E. Coli in which ActA is expressed moves in host cell cytosol
III. Listeria lacking the ActA gene fail to move inside the host cell cytosol.
IV. ActA has 3 transmembrane domains
V. Arp2/3, when activated, nucleates a branched actin network
a. I and II
b. II and III
c. I and III
d. III and IV
e. I and V
Answer:
b. II and III
Explanation:
The Actin assembly-inducing (ActA) protein is an integral membrane protein localized on the bacterial surface. It has been shown that ActA is necessary and sufficient to induce bacterial movement within host cells, regardless of other proteins. The function of the ActA protein for bacterial movement within host cells was discovered by identifying mutant Listeria bacteria for the gene encoding this protein which were unable to spread from cell to cell. Subsequently, by inducing mutations in other genes of the bacterial genome, researchers discovered that actA was the only protein involved in the actin assembly, which is required for cell-to-cell spread.

A stream that flows into two different rivers is part of two
A reservoirs.
B. tributaries.
C. divides.
D.
watersheds.
Answer:
Tributaries
Explanation:
I wound think that they would be branching of so thats what i would say
A water body that flows on the surface of the earth is called a stream. The river is a larger water body compared to streams. Stream is shallow likened to river volume.
A stream that flows into two distinct rivers is part of two:
Option b. Tributary
This can be explained as:
A reservoir is a lake that reserves the water either created naturally or artificially.A stream that merges into the river is called tributary or affluent.A watershed is a drainage bay where the water from precipitation gets accumulated and drains to common river or water bodies.Therefore, a tributary is a stream that flows into two different rivers.

Which of the following is an example of a positive feedback loop:
I. As the Earth’s surface warms due to global warming, water evaporation from a lake will initially increase. As the lake level drops, the surface area decreases and evaporation also decreases.
II. Water vapor from ocean evaporation creates low altitude clouds. Sunlight that would normally warm the Earth’s surface is instead reflected back to outerspace.
III. Water vapor from ocean evaporation creates high altitude clounds. Heat that would typically escape the atmosphere into outer space is trapped in the atmosphere instead.

According to the USDA, a "consists of a community of individuals who pledge support to a farm operation so that the farmland becomes,
either legally or spiritually, the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits
of food production."
-sustainable operation
-farmers' market
-farmers' cooperative
-CSA
Answer:
The correct answer is CSA.
Explanation:
Community Supported Agriculture (CSA) is an alternative model for the distribution of agricultural products directly from the farmer to the consumer, it consists of a group of people who form a cooperative to grow and consume food. Through this socio-economic model, consumers lend their support to producers, in exchange for a direct and regular delivery of biological products, that is, producers and consumers support each other and share the benefits and risks of food production.
