Answer:

Germplasm are living genetic resources such as seeds or tissues that are maintained for the purpose of animal and plant breeding, preservation, and other research uses.

Explanation:

Germplasm contains the information for a species' genetic makeup, a valuable natural resource of plant diversity. Agriculture benefits from uniformity among crop plants within a variety, which ensures consistent yields and make management easier.

A gene (gene X) undergoes a mutation which converts if from wild-type to mutant. Then a second mutation in the gene Y occurs whi
Tcecarenko [31]

Answer:

b. forward mutation, suppressor mutation

Explanation:

When the nucleotide sequence of an organism is altered, it is called as mutation. It can be caused by DNA damage or replication errors. In forward mutation, the wild type allele is converted to a mutant version such that the gene product is non functional or its not produced at all. Suppressor mutation is the second mutation which reverses the phenotypic effects of the previous mutation. This process is called as synthetic rescue.

Since here gene X was converted into a mutant form by the mutation, it had undergone forward mutation. When gene Y was mutated, the function of gene X was  restored which ultimately also restored the phenotype hence it is an example of suppressor mutation.

Obligate symbiotic fungi that form associations with plants by entering their cortical cells without invading the plant cells me
kow [346]
Obligate symbiotic fungi that form associations with plants by entering their cortical cells without invading the plant cells membrane are called endomycorrhizae and include the genus Glomus. Many plants form associations called mycorrhizae with fungi that give them access to nutrients in the soil, protecting against disease and toxicities.  In these associations the fungi are integrated into the physical structure of the root, where the fungi colonize the living root tissue during active plant growth.

Corn is a popular feed for pigs because it is high in carbohydrates. However, it has a very low level of the amino acid lysine,
Keith_Richards [23]

Answer:

Lysine is important because it is very essential for the body functions of a pig.

Explanation:

Pigs require high levels of lysine, an amino acid. Without enough of this, muscle proteins cannot be formed because amino acids cannot combine correctly. Lysine is essential for body function. Corn diets can only provide pigs with limited lysine and this is not up to what is needed in a pigs nutrition. If the pig is consuming enough lysine then it can use other essential amino acids.

Please answer I really need help
sladkih [1.3K]

Answer:

1. Non-living

2. Reproduce

3. Nucleic acid

4. RNA

5. Protein

6. Capsid

7. Burst

8. Lytic

9. Lysogenic

Explanation:

Viruses are set of organisms classified as NON-LIVING (1) because they do not exhibit the characteristics that living things exhibit. Viruses are incapable of REPRODUCING (2) on their own, and hence, need a living host to infect in order to replicate itself.

In the structural composition of a virus, it is made up of only one type of NUCLEIC ACID (3), which can either be DNA or RNA (4). The nucleic acid is surrounded by a PROTEIN (5) coat called CAPSID (6).

There are two ways a virus can infect its host. First, it can replicate itself causing the host cell to BURST (7) or lyse in a process called LYTIC CYCLE (8). Also, the virus can remain dormant in the host cell and continually replicate with the host cell in a process called LYSOGENIC CYCLE (9).

1. A week after returning from a backpacking trip, four teenagers developed nausea and severe diarrhea. All had consumed untreat
otez555 [7]

Answer:

Explanation:

1) The relationship that exists between the teens and the organism (Giardia) is Parasitism. Because in such symbiotic relationship one species (the parasite-Giardia) benefits while the other species (the host- the teens) is harmed.

2) Plants remove Carbon dioxide (a major green house gas) from atmosphere during photosynthesis. But, if plants are also being removed with increase in use of fossil fuels, the CO2 that escapes the fossil fuels will remain in the atmosphere for longer as there are not enough plants to "suck" them back into a stored form of Carbon. Carbon Dioxide increases green hourse effect thus green house effect will increase and earth's temperature might rise due to this.

3) Without decomposers we would not be able to continue the carbon cycle because we could not release the stored carbon from plants and animals into the atmosphere. Decomposers break down dead material from organism and release carbon dioxide into the atmosphere, where it's available to plants for photosynthesis. Without them, we could not recycle nutrients or carbons in our ecosystem and thus, they are critical for the carbon cycle.
