Birds belong to different species but share similar characteristics. What inference can be correctly drawn about this statement? (5 points)
Group of answer choices
All birds share the same habitat.
All birds produced similar offspring.
All birds reproduce with genetic variation.
All bird species adapt through evolution
Answer:
All bird species adapt through evolution
Explanation:
The correct answer would be that all birds reproduce with genetic variation and adapt through evolution.
Sexual reproduction causes genetic variation in sexually reproducing organisms due to crossing over and a random assortment of genes. Birds can only reproduce sexually and hence. they produce offspring that are genetically different but that might share many similar characteristics.
Evolution refers to the development of complex organisms from simple ancestral ones. Organisms change and evolve as they constantly try to adapt to their changing environments. Hence, organisms of the same species growing in a different environment might end up becoming different species as a result of adapting to their different environments, although they would still have some similarities to one another. In other words, evolution has a tendency to cause speciation.

Compare and contrast an ecosystem driven by photosynthesis to an ecosystem driven by chemosynthesis
Answer:
Chemosynthesis gets its energy from oxidation of inorganic substance, photosynthesis gets its energy from light.
Chemosynthesis could occur just about anywhere there are enough suitable chemicals to oxidize [metabolize], while photosynthesis could occur only when there is sufficient light.

Increased numbers of CAG repeats in the exon of a gene is associated with certain diseases. In a specific gene, the existing CAG codons are in the 'zero' reading frame, in- frame with the AUG initiation codon. The effect of increased numbers of CAG repeats on the encoded protein is:___________. a. to silence of the gene to generate a truncated protein b. to generate a protein with a run of consecutive glutamines c. to generate a frameshifted protein product d. none of the above
Answer:
The correct answer is - option b. to generate a protein with a run of consecutive glutamines.
Explanation:
The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.
So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.

Where did all of the material come from that makes up the trees?
Answer:
Explanation:
The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

Which best matches objects that a scientist would include on a list describing a forest ecosystem?
Answer:
The interpretation has been outlined throughout the summary section below, as per the particular circumstance.
Explanation:
A forest or woodland habitat comprises a large field of soil that is covered by forest vegetation and inhabited by food creatures. Three major forest types occur, namely trees and shrubs plantations, mangrove swamps, as well as deciduous trees. This could be claimed that somehow natural vegetation has become an organic unit consisting of almost all of the aquatic biota, that is, have all organisms, creatures of that area that act throughout accordance because of all the resources of the atmosphere that seem to be non-living.

and learns that they mate for life. She knows that not all animals mate for life and that there are various combinations of mating systems,
Describe two mating systems, and explain why different systems exist.
Answer:
It depends on their life expectancy. There is an bird that is born and dies on the same day (sorry I cannot remember the name) so as soon as they can mate, they mate until death. Not every animal mate for life because they live longer. Animals that mate for life mate because they have a short life so they do this to continue the population.

Which of these factors can help keep a freshwater resource sustainable?
O A. A growing population
O B. A new way of generating freshwater
O c. A new way of polluting water
O D. A growing demand that exceeds renewal rates
SUBT
Answer:
B.
Explanation:
A only increases the demand for freshwater, which worsens the situation.
C pollutes the water, hence making the freshwater unusable, and making it much, much more worse.
D does not change anything but make it more unsustainable.
Hope this helped!
The factors that can help keep a freshwater resource sustainable are a new way of generating freshwater, which is option B, as the growing population, a new way of polluting water, and a growing demand that exceeds renewal rates are all factors that can put a strain on freshwater resources.
What is a freshwater resource?Freshwater is a finite resource, and as the population continues to grow, the demand for freshwater increases. Climate change is also affecting freshwater availability with changes in precipitation patterns and increased evaporation rates. Therefore, it is essential to manage freshwater resources in a sustainable way to ensure that they are available for future generations.
Hence, the factors that can help keep a freshwater resource sustainable are a new way of generating freshwater, which is option B,
