Answer: 1. smallpox.
the common cold and different types of flu.
measles, mumps, rubella, chicken pox, and shingles.
hepatitis.
herpes and cold sores. 2. Most notably, viruses differ from living organisms in that they cannot generate ATP. Viruses also do not possess the necessary machinery for translation, as mentioned above. They do not possess ribosomes and cannot independently form proteins from molecules of messenger RNA. 3. All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion. 4.

In its infective form, outside the cell, a virus particle is called a virion. 5. A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:
1 Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.
2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.
3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism. 6. Host range is determined by the presence of receptors on the cell's surface. Viruses attach only single species and some attack only particular types of cells within a plant or animal. brainliest?

Answer: 1. Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.First,the sun transfers heat to the plants,helping them grow.Animals such as deer who would eat grass,eat plants. 2. Initial Observations What was the health of the ecosystem of Atlas National Park like before wolves were reintroduced? Before the wolves, all species were outside their normal range. The ecosystem was not in equilibrium at all and slowly deteriorating. 3. Wolves are causing a trophic cascade of ecological change, including helping to increase beaver populations and bring back aspen, and vegetation. brainliest?

Answer:
The correct answer is -
1. Archaea are prokaryotic cells. These are one of the two prokaryotic organism domain. the other is eubacteria.
2. Eubacteria cell wall contains peptidoglycan which is composed of sugar and amino acids.
3. Eukaryotic cells have membrane-bound nucleus or organelles. which distinguishes it from prokaryotic cells.
4. All archaea domain organisms found in extreme conditions such as halophiles, extremophiles, and thermophile.
5. The cell wall of the plant is made of cellulose, a polymer of glucose units.
6. Eubacteria are considered to be the first living organism or form found on earth.
7. Fungi cell walls are made up of a chitin cell wall. which is makes it different from eubacteria and plants.
8. Fungi uses absorption to obtain nutrients. Most of the fungi uses haustaurium to absorb nutrients.
9.Fungi are organism that do not fit in other eukaryotic category. Hence they were classified as separate kingdom in 5 kingdom classification.
10.plants are classifies as autotrophs because they make their own food.These autotrophs serve as primary producers.
11.Corals have a symbiotic relationship with algae. Algae provide food for coral through photosynthesis where as coral provide protection to algae.
12.corals are classified as autotrophs due to their relationship with algae.They are mixotrophs generally because they act as autotrophs with association of algae and capture prey by tentacles thus making heterotrophic nutrition.

Chromosome's tightly coiled structure enables them to be
properly segregated during ____
Answer:
Chromosomes are coiled structures made of DNA and proteins. Chromosomes are the form of the genetic material of a cell during cell division. It is this coiled structure that ensures proper segregation of the chromosomes during cell division. During other phases of the cell cycle, DNA is not coiled into chromosomes
Chromosomes' tightly coiled structure enables them to be properly segregated during cell division.
Chromosomes:Chromosomes are coiled structures made of DNA and proteins.Chromosomes are the form of the genetic material of a cell during cell division. It is this coiled structure that ensures the proper segregation of the chromosomes during cell division.During other phases of the cell cycle, DNA is not coiled into chromosomes. It exists as a grainy material called chromatin.
Thus, we can conclude that during cell division chromosomes' tightly coiled structure enables them to be properly segregated.

How many major categories are fossils grouped into?
Answer:
Fossils are remnants or impressions of ancient organisms that are naturally preserved in stone. While there are hundreds of fossil types, they are often grouped into two major categories: Body fossils, which are the preserved remains of plants and animals; and Trace fossils, which are records of an animal’s behavior, such as footprints.
How does an impulse move during reflex arc? *
Answer:
Reflex arcs
Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical impulses to an effector. Effector produces a response (muscle contracts to move hand away).

In the Disease Transmission experiment you will simulate exposure to a "pathogen". Predict whether the rate of exposure (the amount of contacts) will affect an individual’s chance of becoming infected. Explain your reasoning.
Answer:
Yes, the rate of exposure (the amount of contacts) will affect an individual’s chance of becoming infected
Explanation:
Yes, the rate of exposure (the amount of contacts) will affect an individual’s chance of becoming infected
The larger is the rate of exposure to infected individuals, the higher is the probability of a healthy individual to get infected.
Let us suppose , if a healthy individual comes in contact with only other healthy individuals then the individual’s chance of becoming infected will be zero.
(b) Many amphibian species throughout the world are endangered
Suggest three reasons why many amphibian species are endangered
Answer:
The correct answer is - habitat loss, pollution and disease, and climate change.
Explanation:
Many amphibians are endangered due to several reasons including, habitat loss, climate change, pollution and disease, non-native species invasion, and many others. Amphibians are mostly live in damp habitats or moist soil and low-level water and these habitats are destroys due to pollution, deforestation or excess fishing.
Pollution and disease also affect these species most specifically chytridiomycosis, caused by the chytrid fungus was an epidemic for many amphibians. Climate change also affects the temperature and soil quality precipitation of the habitat that not suitable for these species.
Which factor could have allowed the population of black peppered moths to increase in the late 1800s? (1 point)
less rain
less vegetation
Less food
less predation
Natural selection favored the population of black peppered moth. This led to less predation and increased population of black peppered moth.
What is natural selection?The natural selection is the process to adapt and change according to the changing environment by organisms.
Initially there were both white and black peppered moths were present. It was recognized that the camouflage of white moth was not worked in dark forest.
This caused mutation in them and changed their wing color to darker shades.
This led to less predations as they were no more recognizable in dark forest due to their dark wings.
Thus, the correct answer is d.
