Eukaryotic gene regulation takes place through the use of RNA- binding proteins called transcription factors and short regions of DNA that help position RNA polymerase called TATA boxes.
At the organism level, homeotic genes control the differentiation and development of cells during embryonic development.
Transcription factor:Transcription factors are proteins involved in the process of converting, or transcribing, DNA into RNA. Transcription factors include a wide number of proteins, excluding RNA polymerase, that initiate and regulate the transcription of genes. Regulation of transcription is the most common form of gene control.

__________ give you energy and help you feel satisfied after eating.
Answers
Animals, including humans, derive chemical energy from their food to support their metabolism, including their muscular activity.
What is the source of energy from food?The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
Cells release energy from nutrients through the process of respiration. The majority of the time, glucose has already been produced from the food.
Because they work quickly and provide energy as soon as they are taken, carbohydrates—which have 4 kcal per gram—are the foods that are used as an energy source the most frequently.
Therefore, food give you energy and help you feel satisfied after eating.

True. The statement "In terms of plant life, this biome is extremely high in diversity, but there are very few animals that live here" accurately describes a tropical rainforest biome.
What is tropical rainforest biome?Tropical rainforest biome is known for its high level of plant biodiversity and relatively low number of animal species compared to other biomes. Tropical rainforests are home to a wide variety of plant species, including trees, shrubs, and epiphytes, but the dense vegetation and high rainfall make it difficult for many animal species to establish themselves.
However, the few species that are able to survive in the rainforest typically have specialized adaptations that allow them to thrive in this unique environment.

a. xylem
b. companion cells
c. sieve elements
d. epidermis
Answer: b. companion cells
Explanation:
The xylem and phloem are the vascular tissues in plants. Their function is to transport water and sugars respectively to all the parts of the plant body. Xylem is only involved in water transport. Companion cells and sieve elements are the two components of the phloem. The companion cells are the storage house of sugars they have a role in movement of the sugars in and out of the sieve elements. They take up sugars via active transport by using their transmembrane proteins. The companion cells will show major fluorescence as these are the reservoir of sugars.
In a few months, you receive a brief note from the breeder that he checked the four offspring and three have the purple trait and one has the white trait. Since only four offspring were produced, there are not necessarily enough offspring to observe the ratio you predicted. What is the probability of observing three purple and one white offspring: If the purple parent is Pp
Answers
Complete question:
1) Inspired by Gregor Mendel, you visit a local greenhouse to see what a pea plant looks like in person. You spot a plant in the corner and immediately notice that it exhibits the purple trait of the flower color character. This character is controlled by one gene with two alleles, the dominant purple P allele, and the recessive white p allele. Identify what you know for certain based on your observation. Check all that apply.
You know the genotype of the plant. This plant has at least one copy of the P allele.This plant must be heterozygous with respect to the flower color gene.You know the phenotype of the plant.2) In another corner of the greenhouse, you find another pea plant. This plant, however, exhibits the white trait of the flower color character. The greenhouse plant breeder approaches you and mentions that he plans to cross-fertilize the two plants that you have seen. He offers to let you know how the offspring turn out. Without realizing it, the breeder is actually conducting a
dihybrid cross testcross monohybrid cross3) If you were able to examine hundreds of offspring from this cross, what ratio of purple flowers to white flowers would you observe:

If the purple parent is Pp? ----------If the purple parent is PP? ----------5) Based on the four offspring observed, you --------- (can/ cannot) know for certain whether the purple parent is Pp or PP.
Answer:
1)
This plant has at least one copy of the P allele. Because the plant is purple and the P allele is the one that codifies for this color. You know the phenotype of the plant. You can see that the plant has purple flowers, so you know its phenotype regarding flower color.2) A test cross
3)

if bread is exposed to air at room temperature, fungi inevitably colonize it. what does this say about the presence of fungal spores in our environment?
Answers
Answer:
This supports the fact that fungal spores exists in the atmosphere or air
Explanation:
Fungi is a kingdom of living organisms that have distinguished characteristics from plants and animals. They propagate themselves using structures called SPORES. Some of these spores are able to withstand extreme or adverse unfavorable conditions and germinate when conditions are favorable. Most fungal spores are air-borne i.e are dispersed by air.
According to the information in this question, Fungal spores will colonize bread that is exposed to air at room temperature. This implies that fungal spores are present everywhere in the atmosphere looking for opportunities to germinate. The bread is a place conducive for fungal growth due to the presence of nutrients and a favorable temperature.
Compare salt marshes and mangrove forests and explain why mangrove forests are such critical habitats on high energy coasts.
Answers
Answer:
Explanation:Coastal wetlands in the southeastern U.S. provide many important ecosystem goods and services. In addition to supporting important fish and wildlife habitat, they maintain coastal fisheries, store carbon, improve water quality, protect coastlines, and provide recreational opportunities. In many ways, coastal wetlands are dynamic and resilient ecosystems; however, they are being subjected to tremendous environmental change at the regional (e.g., hydrologic alterations, nutrient enrichment) and global scale (e.g., climate change).
One aspect of global change that is expected to have a substantial impact on coastal wetlands is winter climate change. Salt marshes and mangrove forests are common coastal wetland ecosystem types that occupy similar estuarine environments but have different climatic tolerances. In warmer climates, mangrove trees often outcompete salt marsh grasses. However, mangrove forests are sensitive to freezing temperatures, and within the region, mangrove forests are currently found only in Florida, Louisiana, and Texas (though isolated individuals have been reported in Mississippi). Salt marshes are more dominant along colder coastlines where mangroves are not able to survive freeze events. Future climate change is expected to result in increased winter temperatures and, potentially, reductions in the intensity of freeze events which could lead to mangrove forest replacement of salt marsh in parts of the Gulf of Mexico and southeastern Atlantic coast.
From a functional perspective, salt marsh grasses and mangrove trees are foundation species that control ecosystem dynamics and, in stressful and highly dynamic environments, provide the structural properties needed by other species; hence, the ecological and conservation implications of grass-to-tree conversions in coastal wetlands could be large (in both positive and negative ways). Dr. Mike Osland, USGS Research Ecologist and GCPO LCC staffer, along with 4 collaborating scientists, has initiated a study that addresses the following question: how might winter climate change impact the distribution and abundance of salt marshes and mangrove forests in the southeastern U.S.?
Their results begin to illustrate the vulnerability of salt marshes in the southeastern U.S. to mangrove forest expansion and quantify the amount of salt marsh habitat within each state that could be impacted by mangrove forest expansion under various winter climate change scenarios. The preliminary results are striking in terms of the potential for mangrove forest range expansion and coastal marsh displacement in the region. The hope is that these analyses stimulate additional discussion, research, and planning regarding the potential ecological and conservation implications of winter climate change for coastal wetlands in the southeastern U.S.
Answer:
Salt marshes are coastal wetlands found throughout the world on protected shorelines and on the edges of estuaries where freshwater mixes with seawater.
Mangrove forests are those which contain Mangroves which are trees and shrubs that grow in saline (brackish) coastal habitats in the tropics and subtropics.
