In a density-dependent population, an increase in which of the following will most likely lead to an increase in population density?
Birthrate
Carrying capacity
Death rate
Emigration
Answers
Answer:
birthrate
Explanation:
In a density-dependent population, an increase in birthrate will most likely lead to an increase in population density. So, the correct option is A.
What is population density?Population density is the number of people in a given area of land. It primarily applies to people, yet occasionally it also does to other living things. That is a crucial geographic phrase. The amount of people who live in an area per square kilometer, or even other unit of land area, is referred to as population density.
We must divide the population's number by the area's size to determine the population density. Population Density is therefore equal to the number of people divided by the land area. Square miles or square kilometers should be used as the measure of land area. If we need to calculate the density of a relatively small place, then can use square feet or meters.
Therefore, the correct option is A.

Explain how hormones recognize their target cells
Answers
Answer:
A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.

Briefly explain how an animal's role in the agricultural industry determines its most desirable traits as livestock
Answers
Answer:
The livestock species play very important economic and socio-cultural roles for the wellbeing of rural households, such as food supply, source of income, asset saving, source of employment, soil fertility, livelihoods, transport, agricultural traction, agricultural diversification and sustainable agricultural production. The aim of this work was to identify and characterize the different roles that livestock and livestock species play in rural communities of Timor-Leste, highlighting the importance of animal production for the wellbeing and rural development, and relate the functions performed by livestock production with economic, social and cultural attributes of the communities. The data used in this study were collected in 2011 through a questionnaire survey in three rural communities in the district of Bobonaro, namely in a mountain area, an irrigation plain and a coastal zone, and were complemented with secondary data. Livestock production in Timor-Leste is predominantly familiar being chickens, pigs, goats, cattle, horses, buffaloes and sheep the main species. Beyond the economic function, each livestock species also performs social and cultural functions.

20. Frigatebirds have webbed feet and spend much
of their life flying over the ocean but never land in
the water. What does this fact suggest about the
evolution of these physical and behavioral traits?
Answers
Answer:
Evolution changes the abilities of the Frigate birds.
Explanation:
The Frigate birds have webbed feet because they live in the ocean and unable to fly due to its big weight. Before the evolution, the Frigate birds lives in the ocean due to their large body weight but with the passage of time, evolution occurs that leads to formation of flying ability in the bird so now the bird have the old characteristics of their ancestor as well as new abilities in the physical traits of the Frigate birds due to the evolution.
If a specific kind of protein is not continually used by a cell, the gene for that protein is _________________________.
Answers
Answer: what are the answer choices?
Explanation:
Answer:
The gene for the protein is turned on and off at different times.
Explanation:
The turning on and off of the gene is described as gene regulation. This process is important because it enables the cells to react quickly to the changes in the environment.
Note that , this process mostly occur at transcription level during gene expression , and help in determining the amount of protein made by a gene.

8. Two heterozygous purple flowered plants are crossed.
What percentage of the offspring are purple?
white?
Answers
Answer:
75% chance of purple, 25% of white
Explanation:
Heterozygous means having two different alleles of a gene
This must mean they are Purple dominant and white recessive
This will be represented as Pw
[tex]\left[\begin{array}{ccc} &P&w\\P&PP&Pw\\w&Pw&ww\end{array}\right][/tex]
This, called a punnet square, calculates the probability of the gene outcome. The top Pw represents one parent and the Pw on the left side represent the other.
In the diagram, each combo of letters ( PP, Pw, Pw, ww ) represents a 25% of what gene the offspring will have. PP means it'll be purple, and so does both Pw's. ww means white flowers though because there is no dominant trait and only recessive. This is the only way for a recessive trait to appear in a child.
Therefore there is a 75% chance of the offspring having purple flowers and a 25% chance of the offspring have white flowers.

Each one of the boxes on the Punnett square represents what probability of a offspring genotype?
A-10%
B-0%
C-1%
D-25%
Answers
Answer: D - 25%
Explanation:
There are four boxes in this punnet square, each one an equally possible genotype for the offspring.
Each box then has a 1/4 (25%) possibility of being the offspring's genotype.
Each one of the boxes on the Punnett square represents a 25% probability of an offspring genotype. Therefore, option D is correct.
What are a punnet square and its uses?Every possible outcome of a genetic cross between two individuals with known genotypes is listed in the Punnett square, a table. In its simplest form, the Punnett square is a square divided into four quadrants.
A Punnett square can be used to determine the expected frequencies of various genotypes in the children of two parents. A Punnett square can be used to forecast the percentages of phenotypes that will come from known genotypes in a cross' offspring.
Thus, each one of the boxes on the Punnett square represents a 25% probability of an offspring genotype. Therefore, option D is correct.
