The generation of action potentials in neurons located within the ____________ causes them to secrete their hormones
Answer:
The correct answer is - the hypothalamus.
Explanation:
The generation of action potentials or nerve impulses generated in the neurons within the hypothalamus which result in the secretion of the hormones.
Hypothalamus is the part of the brain that plays many roles in the body including homeostasis by the secretion of the hormones which are released due to the nerve impulses generated in the nerves present within the hypothalamus.

Explain why the cell membrane in animal cells is thicker than in plant cells.
How does natural selection explain why some organisms are more likely to survive and reproduce than other organisms?
A. Some organisms inherit traits enabling them to adapt better to the environment.
B. Some organisms acquire traits during their lifetimes that they pass to their offspring.
C. Some organisms do not reproduce as many offspring during their lifetimes.
D. Some organisms die before they reproduce any offspring.
Any heritable characteristic that aids an organism in surviving and reproducing in its environment is referred to as an adaptation. Some organisms are more likely to survive and reproduce than others as some of them inherit traits enabling them to adapt better to the environment.
Why do organisms adapt?To live, all species must adapt to their surroundings. This entails adjusting to survive the ecosystem's climatic conditions, predators, and other species seeking the same food and space.
Organisms with heritable features which enable them to better adapt to their environment relative to other members of their species will be more likely to live, reproduce, and pass on more of their genes to the next generation the theory of evolution by natural selection.
Thus, the correct option is A.

Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male and female reproductive structures d. photosynthetic signals
Answer:
a. a female reproductive structure
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.
Division Antophyta are classified into two (2) main categories and these includes;
I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.
II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.
Fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.

Answer:
Tropism is the force used by the plants to grow in a specific direction.
Explanation:
The movement of plant parts such as shoots and roots etc in a specific direction in response to an external stimulus, this phenomena is known as tropism. Phototropism refers to the movement of upper part of plant body towards sunlight while on the other hand, the movement of roots downward against sunlight is known as geotropism. Both phototropism and geotropism are the types of tropism.

Use complete sentences or list form in order to describe the steps of replication. You must
use the following words and underline them:
Nucleus Helicase
Complementary strand
DNA Polymerase Ligase
Okasaki Fragments 5’ to 3’ Leading strand
Lagging strand
Answer:
Please find the description below
Explanation:
DNA replication involves the duplication of the DNA molecule in the NUCLEUS to yield two identical copies. It involves the following steps:
- DNA molecule (double stranded) is unwound or separated into a replication fork by DNA helicase.
- The DNA, which now comprises of two single strands i.e. one strand that runs from the 3'-5' called LEADING STRAND and other strand that runs from '-3' called LAGGING STRAND.
- An enzyme called DNA POLYMERASE attaches to the DNA and adds nucleotide in a bidirectional pattern i.e. adds nucleotide to the leading strand in a 5'-3' direction, then adds short pieces of DNA called OKAZAKI FRAGMENTS to the lagging strand.
- The synthesis of nucleotides by DNA polymerase follows the COMPLEMENTARY BASE PAIRING rule i.e. A-T, G-C.
- Another enzyme called DNA LIGASE joins the okazaki fragments together into a whole DNA.
At the end of replication process, two identical copies of DNA is produced, with each containing one old strand and one new complementary strand.

Why phage is consider as a nanomachine?
Answer:
phages are non-living biological entities that can produce numerous copies of themselves, forming ordered three-dimensional structures on a nanometre scale
Explanation:
A phage (i.e., a bacteriophage), is a virus capable of infecting and replicating within bacteria. Bacteriophages are composed of proteins forming a capsid that encapsulates the genetic material (either DNA or RNA genome), which may contain a variable number of genes. Bacteriophages, and viruses in general, can be considered nanomachines capable of producing numerous copies of themselves with high fidelity by utilizing the molecular machinery of the host bacterial cell. In biotechnology, it has been proposed to exploit the knowledge about bacteriophage reproduction to design diverse nanostructures.
