How are viruses different from Bacteriophages?
Answer: It's different because it is a bacteria eater.
Explanation: A bacteriophage is a type of virus that infects bacteria. In fact, the word "bacteriophage" literally means "bacteria eater," because bacteriophages destroy their host cells. All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.
Hope this helps! Stay safe :))))
Answer:
Even bacteria can get a virus! The viruses that infect bacteria are called bacteriophages.
Explanation:
A bacteriophage is a virus that infects bacteria.
A bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material.
What might happen to the organisms in the food web below if the number of phytoplankton and vegetation drastically decreased?
Answer:
i don't now exactly how to answer this when theres' no food chart however as the vegetation and phytoplankton drastically decrease everything decreases. This is because the producer the bottom of the food chain also known as vegetation is the prime source of energy in every food chain. when there's scarce amounts of producers a domino affect will occur. There will be no food for the first consumers to eat leading their population to decrease and the animals that feed off them will decrease then the animals that feed of them will decrease and so on until the organisms of the food web die out.

Explain how this experiment disproves the theory of spontaneous generation.
Answer:
The theory of spontaneous generation suggested that the living organisms can come from inanimate objects, however, it is an obsolete theory that is disproved by many experiments. The very first experiment that disapproved it was the experiment by Francesco Redi in 1668.
He demonstrated that maggots come from the eggs of flies instead of rotting meat. He placed raw meat inside of every jar. Half the jars he left open and the other half, he covered with mesh. In open jars, he found maggots after some time but covered jars have no maggots. That proved that the maggots come from eggs of flies rather than rotten meat.
The presence of flies on the meat is responsible for the production of maggots in meat.
This experiment disproves the theory of spontaneous generation because maggots are produced from the flies not the rotten meat. According to spontaneous generation, living organisms are formed or develop from nonliving matter.
So by performing this experiment we can see that maggots are formed when the flies feed on the rotten meat otherwise no maggots are present if the flies are not present there so that's why we can conclude that this experiment rejects the theory of spontaneous generation.

Jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. Which of the following would make the best project?
Answer:
a video that shows penguin species that have different mating dances
Explanation:
The question is incomplete as it does not have the options which are:
a video that shows a large river that has penguin populations on both sidesa video that shows penguin species that have different mating dancesa video that shows a penguin that is laying eggsa video that shows penguins in a tidal pool and an open oceanAnswer:
a video that shows penguin species that have different mating dances
The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.
The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.
In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.
Thus, the selected option is correct.
A video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.
What is Population?A population is defined as the complete set of individuals, whether that group includes a nation or a group of people with a common characteristic which is the pool of individuals from which a statistical sample is drawn for a study. .
It is described as a unit of biological community made up of a permanent group of an interbreeding individual of a species found in a space or geographic region at a particular time. Population are of three types of population pyramids created from age-sex distributions-- expansive, constrictive and stationary.
Thus, a video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.

Why are human populations not limited by the carrying capacity of their ecosystems?
Answer:
humans use their knowledge to locate resources.
Explanation:
The carrying capacity can be defined as the maximum number of individuals in a population of a species that an ecosystem or region can support on the basis of availability of water, food, habitat and other needs necessary for survival. Sometimes, the population of the species increases exponentially exceeding the carrying capacity of an ecosystem when the resources available are surplus.
The human populations are not limited by the carrying capacity of their ecosystem this is because of the fact human beings possess special intellectual and thinking abilities which make them capable of availing themselves resources. They posses knowledge which allows them to search, and find resources even from the earth extreme locations not suitable for survival.

process represented in the diagram below?
1. a gamete produced in meiosis
2. a white blood cell engulfing bacteria
3. a zygote being produced in an testes
4. a human repairing damaged tissue
a gamete produced in meiosis is the correct answer .
What is meiosis ?Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

(1) What will be the frequency of the recessive allele in a population of 100 kangaroos if there are 50 dominant alleles?
a. 150
b. 0.75
c. 0.50
d. 0.25
(2) If the frequency of the recessive allele for a gene is 0.3, calculate the expected frequency of heterozygotes in the next generation if the population is in Hardy-Weinberg equilibrium.
a. 0.42
b. 0.21
c. 0.70
d. 0.30
Answer:
1. Option c
2. Option a
Explanation:
1. If there are 50 dominant alleles, this represent the frequency of dominant alleles p = 50/100 = 0.5
Using the formula p+q = 1 we can solve for the frequency of the recessive alleles q = 1 -0.5 = 0.5 = 50%.
2. the frequency of the recessive allele for a gene is 0.3 which is q = 0.3
From the Formula p + q = 1 we can solve for p the frequency of the dominant alleles = 1 - 0.3 = 0.7
To calculate for the number of heterozygotes, we use 2pq = 2 x 0.7 x 0.3 = 0.42
