Answer:
This distribution of species supports Gleason´s Individualistic concept of a community.
Explanation:
This theory was proposed by Gleason and it states that plant species respond individually to environmental factors that continuously change at spatial and temporal levels. This means that the combination and distribution of plants in a certain point or area are unique because each vegetable species has a different distribution pattern and a different tolerance and abundance rate. Hence each species´ response curve to a certain gradient has its own shape and size and it different from other species curves.
Plants assembly growing in an area is the result of environmental conditions and migration rate of species. As every area is continuously getting propagules of different species, the survival success of each plant depends not only in environmental factors, but also depends on the tolerance to other new species and their interactions. This combination along a gradient always results in different composition and abundance of species. This is why a sample can not be confined to a clearly defined vegetable community.
This point of view is known as individualistic or continuum concept of vegetable community. Gleason believed that vegetable species were distributed as a continuum and that communities can not be identified as combinations of associated species that repeat in space.
You are studying lipoprotein processing in a strain of mutant mice. You find that these mice synthesize the same apolipoprotein composition contained in lipoproteins made in the liver and the intestines, whereas, in wild-type mice there are 2 different sized apolipoproteins in these same tissues. Examination of the mRNA processing in the mutant mice would most likely show a defect in which of the following processes?A. alternative polyadenylationB. alternative splicingC. differential cappingD. posttranscriptional modification converting a U to a T residueE. RNA editing
Answer: Option E -- RNA Editing
Explanation:
It should be noted that, RNA editing can be defined as a molecular process via which some cells can make discrete changes to specific nucleotide sequences within an mRNA molecule after it has been generated by RNA polymerase. In addition, we have two major types of RNA editing with 1 being a C-to-U change catalyzed by cytidine deaminase that deaminates a cytidine base into a uridine base, e.g C-to-U editing is with the apolipoprotein B gene in humans. ApoB-100 is expressed in the liver and apoB-48 is expressed in the intestines. The B-100 form comprises of a CAA sequence that is edited to UAA, a stop codon, in the intestines.

describe classification as a work in progress discuss the characteristics of the three domains: Bacteria, Archaea, and Eukarya describe classification by cladistics summarize how molecular evidence reveals species relatedness identify the structures and shapes of viruses describe different types of viral infections
Answer:
Bacteria, Archaea, and Eukarya represent the three domains of life by which all living organisms are classified. This type of classification was coined by Carl Woese et al. (1990). Archaea and Bacteria represent different domains because Archaea is considered to have the evolutionary oldest phenotypic features, while Bacteria species have diacyl glycerol diester lipids in their membranes. On the other hand, the Eucarya domain is composed of organisms that possess a nuclear envelope (membrane).
Cladistics is a biological method used to classify organisms into groups named 'clades'. In this type of classification, organisms are categorized according to the most recent common ancestor. In this regard, it is possible to find the most recent common ancestor by using nucleotide differences between taxa.
Viruses can be classified in a similar manner to the cellular organisms above described. Viruses are categorized according to morphological features, type of nucleic acid (DNA or RNA) by which they are composed, mode of replication, host organisms, etc. Viruses may also be classified according to the type of disease that they cause. There are viruses that cause chickenpox, rabies, influenza, old sores, Ebola, AIDS (HIV), Severe acute respiratory syndromes (SARS), etc.
Describe classification as a work in progress
Since it reflects the most current understanding of how living things are related, new discoveries can change the way living things are classified also something is always changing.
Discuss the characteristics of the three domains: Bacteria, Archaea, and Eukarya
Bacteria includes common bacteria, Eukarya includes the four kingdoms: plants, animals, fungi, and protists. Archaea includes some of the oldest organisms on the planet.
Describe classification by cladistics
Cladistics depict hypothesis about how organisms are related based n their ancestors and descendants.
Summarize how molecular evidence reveals species relatedness
they are classified by DNA now instead of physical features.
Identify the structures and shapes of viruses
the shape can be helical,envelope,icosahedral,complex.
Describe different types of viral infections
lytic infection: virus enters the host cell, replicates copies, and destroys the cell to get out and spread to others/ Lysogenic infection: virus incorporates its DNA into the DNA of the cell. They both attach to host cells and use the cells resources to replicate genetic materials and parts.

Some eco-friendly resources that you can look for when buying your first vehicle, that it is not powered by fossil fuels, so it can be powered by electricity or hybrid, with that, it is still necessary to continue using your car correctly so as not to emit other pollutants, to know more.....
Ecological carA hybrid ecological car, powered by solar energy and even electricity, brings numerous benefits to the environment. These vehicles are the ones that mix the use of electricity and fuel to move around. Generally, at low speeds, electricity is used as the main form of movement and gasoline only kicks in when high speeds are required.
The models powered by solar energy and electricity do not use fuel to move. The great advantage of this for the environment is the reduction in the emission of pollutants, such as CO2, which actively participates in the greenhouse effect and consequent global warming. With the use of ecological vehicles, our planet must become a better place to live.
With this information, we can conclude that choosing a car powered by renewable energy is the best option to choose, to maintain the ecological balance and health of the planet.

Suppose that you are in charge of designing a fracking job site. Which of these locations would be most ideal for the site?
Answer:
B. On a flat, vacant plot in the outskirts of the city
Explanation:
Fracking, also known as hydraulic fracturing is a drilling method used in the oil and gas industry of most countries. It is the process whereby natural gas and petroleum is extracted from deep down the Earth. A crack is made in the rock layers, followed by the injection of a liquid called fracking liquid, which is usually water, at a very high pressure.
The process of fracking has serious environmental side effects e.g. release of harmful gases, noise pollution, water contamination etc. and hence, when choosing a fracking site, environment's sustainability and safety of people should be taken into account. This is why a fracking site cannot be designed in a residential city or around a neighborhood. The site should rather be designed in a location where it would pose a minimal environmental threat to the people e.g flat, vacant plot in the outskirts of the city

2)Hypotonic solution-More concentration of solvent in the solution than in the grape.
3)Hypertonic solution-More concentration of solvent in the grape than in the solution.
Now,
a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.
b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.

A Mesopotâmia e o Egito antigo foram as primeiras culturas que desenvolveram métodos de irrigação. Um dos métodos eram os canais, mas quando não funcionavam, os egípcios precisavam inventar ferramentas para bombear água do Nilo e de outras fontes. E dessa forma, desenvolveram o sistema de canais. Os governantes egípcios colocaram uma enorme importância no sistema de canais do país e os governantes regionais foram responsáveis pela escavação e reparação das estruturas. Os canais usavam a água do Nilo quando o rio estava na época da cheia e inundava algumas terras...

what are sex hormones?why are they named so? state their function.
Answer:
Sex hormones or hormones of the reproductive organs are certain cells in the reproductive organs that produce hormones.
The testis produces testosterone,the male sex hormone,and the ovaries produces oestrogen and progesterone, the female sex hormones.
In a sexually mature male,testosterone influences sexual behaviour, and together with FSH,regulates sperm production in the seminiferous tubules of the testes.
Sexually matured females undergo a regular 4-week reproductive or menstrual cycle during which a mature egg is released.This cycle is regulated by oestrogen and progesterone. During pregnancy, progesterone inhibits egg production (ovulation),brings about the development of the placenta and prevents the uterus from contracting....I hope this answers your question...

What effect does insulin have on the body? It raises blood-sugar levels. It lowers blood-sugar levels. It raises glucagon levels. It lowers glucagon levels.
it regulates blood sugar level.
Explanation:
Insulin helps control blood glucose ( sugar) levels by signaling the liver and muscle and fat cells to take in glucose ( sugar) from the blood. Insulin therefore helps cells to take in glucose (sugar) to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose ( sugar) and store it as glycogen.

What are the characteristics of fish?
A fish is classified as a vertebrate because it has a vertebral column. There are different types of fish, such as cartilaginous fish and bony fish. In cartilaginous fish, the endoskeleton is made up of cartilage, and this is seen in some large deep-sea animals such as sharks.
Bony fish such as Labeo rohita have endoskeletons made up of bones. This bone is stronger and harder than the cartilage. Most deep-sea animals lack bony skeletons because the pressure exerted on the body at that depth causes them to sink; this is why they evolved in this manner. Some fish can store an oil-like structure that helps them maintain body functions. Some have an air bladder that maintains the proper position.
Hence, the fish does breathe through its gills. The outer scales protect themselves from the outer environment. Fins are for creating balance and protection. Mouth and eye is for predation.

D. Cell, tissue, organ, organ system, organism
The correct order of organization in animals is Cell, tissue, organ, organ system, organism—that is what is written in the option D. The cell is the first to form, followed by tissue, and finally organs and organ systems.
What is the organization of an animal?At the early stage, unicellular individuals were seen, and later, due to development, multicellular individuals were developed. The unicellular organism has only cells, then those cells unite to make a tissue, and in a tissue all the cells have the same function. An example is epithelial tissue, which is made up of many epithelial cells.
Tissues combine to form an organ, and organs combine to form an organ system. An example is an organ such as the liver that is made up of many tissues, but all tissues perform certain functions that are required for the liver, and in the same way, the organ system and the organism are developed.
Hence, the correct order of organization in animals is cell, tissue, organ, organ system, organism—that is what is written in the option D.
