Answer:
This question lacks options, the options are;
A. parietal layer.
B. serous membrane.
C. nuclear membrane.
D. mucous membrane.
The answer is B
Explanation:
The serous membrane is a covering membrane found in living systems. The serous membrane covers the surfaces of certain structures in the body such as heart, lungs etc. where they secrete lubricants that reduce friction during movement.
The structure of the serous membrane is composed of a sheet of simple squamous epithelial cells (secretes the lubricants) that folds onto itself to form a double layer. The layers are joined by a connective tissue.

Compare salt marshes and mangrove forests and explain why mangrove forests are such critical habitats on high energy coasts.
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.

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
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 ----------4) 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? ----------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 the purple parent is PP → 1:0 (100% heterozygous purple flowers, Pp)If the purple parent is Pp → 1:1 (50% Purple Pp, and 50% white pp)4)
If the purple parent is Pp? 3/4 = 75% purple and 1/4 = 25% whiteIf the purple parent is PP? 4/4 = 1 = 100% purple and 0 white5) Based on the four offspring observed, you CAN know for certain that the purple parent is Pp.

A plasmid contains a multiple cloning site inside the coding region of the lacZgene and also contains an ampicillin resistance gene at a separate locus. When cells are transformed with a successfully recombinant plasmid containing a piece of DNA cloned into the multiple cloning site, what color will the colonies be when grown on an agar plate containing ampicillin and X-gal
Answer:
The correct option is white.
Explanation:
As the options are not given, the options are found online and are as follows;
(a.) green (b.) white (c.) colonies will not grow (d.) blue (e.) clear
Out of this, white is the true option because in recombinant plasmid lac Z gene is disturbed and cannot produce beta galactosidase enzyme and there is no hydrolysis of x gal and no blue so recombinant plasmid gives white colonies)

What does each daughter cell inherit during binary fission?
A) half the chromosomes of the original cell
B) a unique variation of the parent cell’s primary DNA
C) twice as many chromosomes as the original cell
D) an identical copy of the parent cell’s primary DNA
Answer:
an identical copy of the parent cell’s primary DNA
Explanation:
In this form of cell division, a cell replicates its DNA, increases in size, and divides into two daughter cells. Each daughter cell receives one copy of the replicated parental DNA.
During binary fission (d), daughter cells receive an exact copy of the parent cell's main DNA.
What is DNA exactly?Definition. Deoxyribonucleic acid, commonly known as DNA, is indeed the molecule that contains the genetic information necessary for an organism's growth or operation. The structure of DNA consists of a double helix, which is made up of two linked threads that loop around one another to form a twisted ladder.
Who created the DNA?Many people think that the 1950s saw the discovery of DNA by English physicist Francis Crick & American biologist James Watson. This isn't in fact the case. Rather, Swiss chemist Miescher made the first official discovery of DNA in the late 1860s.

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?
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.
