________ is a compound produced by sponges that can kill ________.
Toxins is a compound produced by sponges that can kill predators
Sponges are fascinating marine creatures known for their filtering capabilities and unique adaptations. While most sponges are filter-feeders, relying on trapping bacteria and other food particles, there are also carnivorous species which feed primarily on tiny crustaceans through the use of sticky threads or hooked spicules. These can act as mechanical defenses, making sponges less palatable to potential predators. Additionally, some sponges host photosynthesizing micro-organisms as endosymbionts.
One compound that has been identified in some sponges, which has the potential to be useful in pharmacology, falls under the category of secondary plant compounds. While typically associated with plants, similar compounds can be found in various animals. In the case of sponges, these compounds can be toxic to predators, and, interestingly, some of them have shown potential as pharmaceuticals due to their bioactive properties.
Although the student's question is incomplete as it does not specify which compounds and what they may kill, secondary metabolites produced by sponges and their symbionts have been researched for their antimicrobial properties and could potentially be developed into drugs that can kill harmful bacteria, fungi, or even cancer cells.

Why is it possible to detect the pungent odor of ozone after a lightning storm?
The pungent smell of ozone after a lightning storm is caused by the formation of ozone from oxygen due to the electric discharge from lightning, leading to ozone's characteristic sharp odor.
The pungent odor of ozone detected after a lightning storm is due to the formation of ozone from oxygen during electrical discharges. When a lightning strike occurs, the high energy from the electric discharge breaks the chemical bonds of atmospheric oxygen (O₂), creating free radicals. These oxygen radicals then recombine to form ozone (O₃), an allotrope of oxygen with a characteristic sharp smell that is often likened to chlorine bleach. Ozone can be hazardous in high concentrations, causing headaches, burning eyes, and respiratory irritation.

Meiosis, which occurs during sexual reproduction, allows for a great variety of possible gene combinations. Which of the following can increase genetic variation during meiosis?
A. the deletion of a gene caused by an error in chromosomal crossover
B. the transposition of a gene from one place in an organism's genome to another
C. the exchange of genes during chromosomal crossover
D. the duplication of a gene caused by an error in chromosomal crossover
During meiosis, genetic variation is increased primarily through the exchange of genes during chromosomal crossover. This recombination process results in the production of offspring with distinct genetic combinations.
Explanation:Meiosis is a crucial process in sexual reproduction that contributes to genetic variation among offspring. One key mechanism that increases genetic variation during meiosis is chromosomal crossover. This event occurs during prophase I, where non-sister chromatids of homologous chromosomes exchange segments of DNA, forming recombinant chromosomes that carry new combinations of alleles. Therefore, the correct answer to which of the following can increase genetic variation during meiosis is C. the exchange of genes during chromosomal crossover.
Crossover events are the first source of genetic variation in meiosis, leading to offspring having different combinations of genes from their parents. This recombination results in an immense level of potential variation among sexually reproducing organisms. For example, humans have the potential to produce more than 64 trillion genetically unique children.
Final answer:
OPTION C.
Chromosomal crossover during meiosis I is responsible for increasing genetic variation by exchanging segments of DNA between homologous chromosomes, resulting in gametes with unique combinations of genes.
Explanation:
The genetic variation during meiosis is significantly increased by the process known as chromosomal crossover. This event occurs during meiosis I, where homologous chromosomes pair up and exchange segments of DNA. Thus, the correct answer to which process can increase genetic variation during meiosis is C. the exchange of genes during chromosomal crossover. The recombinant chromatids that result from this process contain a unique combination of parental genes that were not present before the crossover, leading to increased genetic diversity in the gametes.

This type of animal tissue can be divided into two types, voluntary and involuntary. 1 epithelial
2 muscular
3 smooth
4 nervous
Answer:
2. muscular tissue.
Explanation:
The muscular tissue is responsible for the movement of the body, body parts, and organs. About 40% of our body is formed of muscles. The muscle tissue is made up of highly contractile muscle fibers.
There are 3 types of muscular tissues - skeletal muscle / voluntary muscle, smooth muscle / involuntary muscle, cardiac muscle.
Skeletal muscles are striped in appearance and hence called as striated muscles. Their muscle activities are under the control of an individual's will. Therefore, these muscles are known as voluntary muscle.
The second type of muscular tissue is smooth muscle. These are located in the inner wall of visceral organs such as the GI tract, reproductive organs, etc. They are smooth in appearance, hence known as smooth muscle. These muscles are not under the control of one's will. Hence it is called involuntary muscle.
The third type of muscle is cardiac muscle. It is exclusively present in the heart. Many cardiac muscle cells are arranged in branches to form a cardiac muscle.
What are purebred organisms
Purebred organisms are individuals from the same species with consistent genetic traits passed down through generations of selective breeding. They can serve as key models for the study of genetics and the preservation of specific traits.
Explanation:Purebred organisms are individuals of a species that possess a uniform set of genes for certain traits as a result of selective breeding or natural processes that encourage inbreeding among genetically similar individuals. Such organisms are bred intentionally to ensure that the traits are passed on to their offspring. To be considered a purebred, both parents must be purebred themselves, often for many generations back, which creates offspring that are genetically uniform.
In biology, organisms broadly encompass living entities that share certain characteristics such as reproduction, growth, and the ability to maintain homeostasis. Within species, reproduction can occur sexually or asexually, with purebred organisms being a result of controlled sexual reproduction, sometimes reinforced by artificial selection in agriculture or dog breeding, for instance.
By understanding how purebred organisms are created and maintained, scientists can preserve desirable traits and study the genetic underpinnings of those characteristics.

How do organisms grow and repair themselves?
Organisms grow and repair themselves through cell division, or mitosis. When an organism is damaged or injured, its cells can also divide and repair the affected area. This ability is vital for their survival and ensures their ability to adapt and respond to environmental changes.
Explanation:Organisms grow and repair themselves through cell division, or mitosis. During mitosis, a single cell divides into two identical daughter cells. This process allows an organism to grow by increasing the number of cells in its body. Additionally, when an organism is damaged or injured, its cells can also divide and repair the affected area.
For example, if you cut your skin, the cells near the wound site will divide to create new cells that fill in the gap and repair the damaged area. Similarly, when bones break, the cells responsible for bone tissue formation will multiply and produce new bone cells, allowing the bone to heal.
Overall, the ability of organisms to grow and repair themselves is vital for their survival and ensures their ability to adapt and respond to environmental changes.

Figure 17-2 shows highest fitness toward the center of the curve. When individuals with an average form of trait have the highest fitness the result is
A-not predicable
B-disruptive selection
C-directional selection
D-stabilizing selection
Answer:
Option-(D): Stabilizing selection.
Explanation:
Stabilizing selection:The process in which a limited or specific number of the species get the chance to evolve through time or they get the best of chances to survive in any environment. As some of the traits may be lost due to the stabilizing form of natural selection.
Diversity is found all across the living beings, but when the process of natural selection follows the stabilizing pathway for selection then it will surely cause the end to diversity among beings.
For example:
The number of eggs that a bird lays and along with the weight of a human being child at the time of birth can be referred to as the stabilizing form of natural selection

The diagram in the question is missing has been attached.
Answer: The first three nucleotide of the complementary DNA strand will be GGC.
DNA contains nucleotide pairs on a sugar phosphate backbone. The nucleotide pairs are connected by hydrogen bonds and each nucleotide pairs with only one other nucleotide. The bases are of two types: purine and pyrimidine. The purine bases bond only to pyrimidine bases. The base pairing follows Chargaff’s rule where adenine forms a pair with thymine by two hydrogen bonds and Guanine forms a bond with cytosine with three hydrogen bonds between them .
