Answer:
A) birds have a large opening where the beak should be.
Explanation:
when scientists turn off the gene that makes beaks in birds, the birds have a mouth where no teeth are present. The birds have mouth because the bird resembles and closely related to the dinosaur. There are some proteins that is responsible for the occurrence of beak but when the genes are turn off these protein stop producing that leads to turn the beak place into mouth.

The brain's complexity arises from the:
A. communication between the hind-, mid-, and forebrain.
B. functions of individual neurons.
C. division between two halves of the cerebral cortex.
D. complex connections of simple pieces.
SUBMIT
The complexity originates from the interaction of several neural circuits that operate across temporal and spatial scales, allowing the brain to adapt to a changing environment and conduct high-level mental activities. Therefore, option (D) is correct.
What is the complexity of the brain?The human brain is an intricate system that operates on multiple temporal and geographic scales, and it is this complexity that gives rise to the intricate molecular, cellular, and neuronal events that, when taken as a whole, constitute the physical and biological foundation of cognition.
This complexity is the result of the interaction of a large number of neuronal circuits that function over a diverse range of temporal and spatial scales. This interaction enables the brain to adapt to an environment that is constantly changing and to perform a variety of high-level mental functions.
Therefore, complex connections of simple pieces leads to complexity.

Which of the following would MOST LIKELY result in decreasing carbon dioxide levels in a lake?
A) an increase in the amount of precipitation
B) a decrease in competition among producers
C) an increase in the number of fish caught from the lake
D) a decrease in the amount of sedimentation entering the lake
Answer: C: an increase in the number of fish caught from the lake
Explanation:
An increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.
What are the effects of carbon dioxide in a lake?Carbon dioxide can have both direct and indirect effects on a lake's ecosystem. Here are some of the effects:
Acidification: When carbon dioxide dissolves in water, it forms carbonic acid, which can lower the pH of the water.
Oxygen depletion: If carbon dioxide levels are too high, it can lead to oxygen depletion in the water.
Algal blooms: High levels of carbon dioxide can also stimulate the growth of algae in the water. This can result in algal blooms, which can have negative effects on the lake ecosystem, such as oxygen depletion, fish kills, and changes in water clarity.
Thus, an increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.

Gametes (SEX CELLS) have ... A. half the number of chromosomes found in the body cells B. twice the number of chromosomes found in body cells C. two sets of chromosomes
Answer:
A. Half the number of chromosomes found in the body body cells
Explanation:
Somatic (body cells) have 2 sets of chromosomes, while gametes have 1 set of chromosomes. Sperm has one set, and an egg has one set allowing both to fuse to create a new organism.
Answer:
[tex]\boxed {\boxed {\sf A. \ Half \ the \ number \ of \ chromosomes \ found \ in \ the \ body \ cells}}[/tex]
Explanation:
Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.
The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with half of the genetic material. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.
They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.
Gametes have half the number of chromosomes in body cells and choice A is correct.
