Answer:
True.
Explanation:
Forestry can be defined as the art and science of creating, development, management, conservation and analysis of the living organisms such as plants, trees and woodlands existing in the forest. This is usually done so as to tap into the environmental benefits associated with the forests and to ensure the continuous existence of wildlife, plant growth and development.
Forest Management is a branch of forestry. The field of forest management typically deals with legal, administrative, financial, economical, technical and social aspects of a forest so as to facilitate the smooth running and operation of the forest reserve.
A sustainable forest can be defined as a forest management process which typically involves the plantation of seedlings to replace trees that are being cut down. Thus, sustainable forestry is mainly focused on keeping the natural forest alive.
Generally, certified wood comes from trees grown in sustainable forests i.e responsibly managed forests.
Hence, certified woods are gotten from trees that were harvested in accordance with sustainable forestry.

Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants
Answer:
Resistance plants increase in number whereas non-resistant plants decreases.
Explanation:
The environment of rain forest is suitable for the fungal growth because of the presence of humidity in the environment and we know that fungi needs moist places for its growth. These fungus attached on the leaves and takes nutrients from that plant that leads to the stunted growth and many cases death of the plant occurs. Some plants have no effect of this fungus due to the presence of resistance in them so if the fungus spreads in the whole forest so the plants which are prone to these fungal infections eliminated from that environment and resistant plants are increase in number.
Answer:
Part B
Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants. One rain forest plant species has a genetic variation that affects its leaf structure. The traits and the descriptions of the plant’s leaves are listed in the chart.

A biologist wants to measure the effect of gene flow between populations. Which of the following investigations will allow her to accomplish this goal?
A)An investigation that determines a change in allelic frequency of a wolf population by theimmigration of a wolf from another population.
B)An investigation that determines the amount of time it takes for genes from a bee to transfer to the flower it fertilizes.
C)An investigation that determines the causes of mutations in genes that one species of guinea pig transfer to another species of guinea pig.
D)An investigation that determines the rate at which an antibiotic prevents a virus from transferring genes to a cat.
Answer:
B
Explanation:
Cause I say so
The investigation that will allow a biologist to measure the effect of gene flow between populations is that a change in allelic frequency of a wolf population by the immigration of a wolf from another population. Thus, the correct option for this question is A.
What is Population?A population may be defined as a group of individuals belonging to the same species living in the same area at a given time. The size, density, abundance, birth rate, death rate, dispersal, etc. are categorized as the characteristics of a population. These characteristics are known as demographic factors.
According to the context of this question, the process of gene flow can be determined by collating allele frequencies of populations. With this mechanism, if the two populations have increased variation in their gene pool, it expresses a lesser amount of gene flow because gene flow increases homogeneity among different populations.
Therefore, the correct option for this question is A.

The modern synthesis combined the concepts of _______ and evolution. If a population is at Hardy-Weinberg equilibrium, the allele frequencies must be _______.
Answer:
The correct answer would be - genetics, constant.
Explanation:
The modern synthesis is a unified evolution theory that came forward by the fusion of Mendelian genetics with Darwinian evolution. It is focused on the genetic basis of evolution as it defines evolution as changes in the allele frequency in the population.
If a population is at Hardy-Weinberg equilibrium, the allele frequencies remain the same in the population unless there is no change is applied to it. It will remain constant only if there is no mutation, infinite population size, no gene flow, random mating, and no selection.
Answer:
1. natural selection
2. constant from generation to generation in the absence of other evolutionary influences.

A. Its length and sequence of nitrogen bases.
B. Where the cell is found in the organism.
C. The position inside of the nucleus.
D. Its shape and color after cell reproduction.
Its length and sequence of nitrogen bases. Therefore, option (B) is correct.
What are nitrogenous bases?Nitrogenous bases are the building blocks of DNA and RNA, which are the genetic material of living organisms. They include adenine, guanine, cytosine, and thymine (or uracil in RNA), and their sequence in DNA determines the genetic code that directs the synthesis of proteins.
The length and sequence of nitrogen bases (adenine, guanine, cytosine, and thymine) in a gene determine the specific sequence of amino acids that make up a protein, and therefore the trait it expresses in a cell. This is known as the genetic code, which is a set of rules that determines how the sequence of DNA bases is translated into the sequence of amino acids in a protein.
The other factors listed (where the cell is found in the organism, the position inside of the nucleus, and its shape and color after cell reproduction) do not directly determine the protein or trait expressed by a gene.

Which of these structure types is composed of alternating layers of lava and cinders?
cinder cone
stratovolcano
shield volcano
none of these
The VEI of a volcano’s eruption is based on
the amount of tephra produced.
the height of the eruption cloud.
a descriptive estimate of the explosion.
all of these.
Answer:
1. Cinder cones
2. All of these
Explanation:
1. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).
2. Volcanic Explosivity Index (VEI) is a numeric scale that measures the relative explosivity of historic eruptions. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The Volcanic Explosivity Index (VEI) was derived to catalogue the explosive magnitude of historical eruptions, based on the order of magnitude of erupted mass, and gives a general indication as to the height the eruptive column reached.

Answer:
Movement of the Asthenosphere
Explanation:
The Asthenosphere is the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur. This convention causes warmer magma in the earth's core to rise and cooler to fall and be heated again. The circular motion caused by this convection is what is thought to cause the Earth's crust to move.
