depth of 8.3 mm were counted. Which of the three statements below are best supported by the data in the graph?
A. Longer beaks are more advantageous in drought conditions
B. No birds with beaks exceeding 11 mm have been counted
C. Beaks shorter than 10 mm are never advantageous
D. A drought can cause some beak depths to disappear
E. The drought caused the bird population to decrease

2. making new forms of human antibiotics.
3. developing a rot-resistant gene for trees.
4. creating pest-resistant crops.
Producing a faster-growing salmon species is an example of scientists using biotechnology to benefit aquaculture. Therefore, option A is correct.
What are biotechnology and its application?Biotechnology is a field of engineering that makes use of biological systems, living creatures, or fragments thereof, to develop or produce various goods. Biomedical, agricultural, and environmental biotechnology fall into three broad groups.
Therapeutics, diagnostics, genetically modified crops for agriculture, processed foods, bioremediation, waste management, and energy production are just a few of the uses for biotechnology.
Thus, producing a faster-growing salmon species is an example of scientists using biotechnology to benefit aquaculture. Therefore, option A is correct.

In science, the prefix “homo” means same. Homologous structures are structures that are set up the same way. Analyze the picture below of the limbs of a human, dog, bird and whale.
Do these homologous structures support the theory of evolution (the idea that organisms evolve from a common ancestor)? Explain your answer.
Answer: There are many examples of body structures that are formed in similar ways during embryonic
development and that share similar patterns of bone structure, even though they take on
different forms and perform somewhat different functions. These structures are called
homologous structures. Homo- means same, and -logous means information, so homologous
means “same information”. Homologous structures mean that the animals share a relatively
recent common ancestor.

Question #20
Which statement best explains one reason why the cells produced from meiosis are different from the
cells produced during mitosis?
A
During meiosis, one cell divides once into two cells, while in mitosis, the cell divides twice into four
cells.
B.
During meiosis, sections of DNA trade places, producing daughter cells different from the parent
cells, while in mitosis, the daughter cells are identical.
с
During meiosis, the genetic material is not copied, while in mitosis, the genetic material is copied.
D
During meiosis, DNA is intentionally mutated, producing daughter cells with new DNA sequences,
while in mitosis, the DNA does not mutate.
The statement which best explains a reason why the daughter cells produced from meiosis are different from the daughter cells produced during mitosis is: B. During meiosis, sections of DNA trade places, producing daughter cells different from the parent cells, while in mitosis, the daughter cells are identical.
Cell division can be defined as a biological process through which a living cell changes from a generalized cell type into a specialized cell type, in order to perform specific functions or tasks in the body of a living organism.
Basically, there are two (2) main types of cell division and these include:
Meiosis: it is a type of cell division (duplication) through which a single cell divides twice to produce four (4) haploid cells (gamete). Thus, the daughter cells are different or unidentical. Mitosis: it is a type of cell division (duplication) through which a single parent cell produces two (2) genetically identical daughter cells.In conclusion, a reason why the daughter cells produced from meiosis are different from the daughter cells produced during mitosis is that , sections of deoxyribonucleic acid (DNA) trade places during meiosis to produce daughter cells that are different from the parent cells, while in mitosis, the daughter cells produced by a single parent cell are genetically identical.

Tom described a certain phase in mitosis as follows: The centromere splits. The paired chromosomes separate and shift to the opposite sides of the cell, which stretches the cell. Which of the following phases will take place just after the phase described by Tom?
Anaphase
Metaphase
Prophase
Telophase
!!!PLEASE HELP!!!
Answer:
I'm not 100% sure, but I think its the Telophase.
Explanation:
The third phase of mitosis is called anaphase. This is when the separation starts. The centromere of each chromosome splits. The spindle fibers shorten and pull the sister chromatids apart until they are on opposite ends of the cell. Each chromatid is now a single, unreplicated chromosome. As a result of this, the cell stretches out. The phase after this is telophase.
