What is Plant pathology?
Plant pathology is defined as the scientific study of diseases in plants which is caused by pathogens and environmental conditions. Organisms which cause infectious diseases such as fungi, oomycetes, bacteria, viruses, viroids, phytoplasmas, etc.
It includes pathogen identification, disease cycle, disease etiology, economic impact, plant disease epidemiology, study of plant disease resistance. Studies also include how plant diseases affect humans and animals, genetics and the management of plant diseases.
Over time, plants become more resistant to the diseases that caused them to live and reproduce.
Thus, the plant species that were resistant to the disease lived and reproduced. So, the correct option is (D).

Compare and contrast food webs based on photosynthesis and chemosynthesis.
Answers
The majority of life on the planet is based on a food chain which revolves around sunlight, as plants make food via photosynthesis.. Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food
Photosynthesis happens with plants on the earth’s surface where sunlight is abundant. Chemo synthesis can happen in the deep sea or places where there is an absence of sunlight. In both food webs, the primary sources both produce energy. A chemosynthetic food web often starts at a sea vent, with chemical energy. Photosynthetic plants get their energy from sunlight, while chemosynthetic bacteria will get their energy from sea vents. The difference is really in the beginning when it comes to where the primary producer gets their energy!

Which statement best describes the concern scientists have about the carbon cycle?
A. The environment is adding carbon faster than humans are adding carbon.
B. The environment is adding carbon slower than humans are adding carbon.
C. Humans are adding carbon faster than the environment can take up and store carbon.
D. Humans are adding carbon slower than the environment can take up and store carbon. Talent
Answers
Answer:
C, Humans are adding carbon faster than the environment can take up and store carbon.
Explanation:
The other answer choices don’t make sense. Humans are impacting the carbon footprint at a much quicker rate & far more heavily so than other organisms. Hope this is correct & helps you out:)
The statement that best describes the concern scientists have about the carbon cycle is : ( C ) Humans are adding carbon faster than the environment can take up and store carbon.
The increase in the rate of industrialization globally has caused a tremendous increase in the rate of fossil fuels been burnt and the increase of gas flaring activities during oil exploration.
The increased burning of fossil fuels adds Carbon more rapidly into the atmosphere than the amount of carbon leaving the atmosphere into carbon deposits.
Hence we can conclude that The statement that best describes the concern scientists have about the carbon cycle is : ( C ) Humans are adding carbon faster than the environment can take up and store carbon.

explain how evolution accounts for diversity of living things
Answers
Answer:
Evolution accounts for the unity and diversity of living things through adaptation. Unity comes from the adaptation and similarities that all organisms share which is DNA, while diversity comes from descent with modification or natural selection.
Evolution is change over time so through the millions an millions of years each organism evolves over time this accounts for diversity bc organism that eventually evolved from cells to sea organisms eventually became land animals

In which organelle can most of the DNA be found In eukaryotic cells?
A. the Golgi bodies
B. the ribosomes
C. the mitochondria
D. the nucleus
Answers
The cell nucleus contains the DNA inherited from each parent, which is used to control the cell's activities and to determine hereditary traits.
The DNA from each parent is housed in the cell nucleus and is utilized to direct cellular activity and define inherited features. Hence option D is correct.
What is DNA?
DNA stands for deoxyribonucleic acid. It is defined as a sophisticated molecule that carries all the data required to create and maintain a creature. All known living things, including many viruses, need DNA, a polymer comprised of two polynucleotide chains that coil around one another to create a double helix, to develop, function, grow, and reproduce.
In terms of genomics, a nucleus is the organelle within a cell that is membrane-enclosed and houses the chromosomes. The nuclear membrane has a variety of pores that enable the selective passage of specific molecules into and out of the nucleus.
Thus, the DNA from each parent is housed in the cell nucleus and is utilized to direct cellular activity and define inherited features. Hence option D is correct.

Explanation:
the nerves in your body are responsible for sending signals to the brain so it can decipher what you are touching and how to react. Ex: when you touch something very hot, the nerves send the signal to the brain, then the brain knows it something very hot, then sends a signal to the body part that touched that super hot thing and is like "GET OFF THAT!

What is Hippo?
The hippopotamus, also known as the hippos, hippopotamuses, or hippopotami (Hippopotamus amphibius), is a big semi-aquatic mammal that is indigenous to sub-Saharan Africa. It is sometimes referred to as the common hippopotamus, Nile hippopotamus, or river hippopotamus.
The hippopotamus is the largest terrestrial mammal after elephants and rhinos. Additionally, it is the largest living land artiodactyl.
The closest surviving relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from whom they separated some 55 million years ago, despite their morphological resemblance to pigs and other terrestrial even-toed ungulates.

BRAINLIST What causes air to move towards the water from the land during the night?
-
The dry air over the land is heavier than the air over the water that contains more water vapor.
The ground retains the heat from the Sun longer than the water.
The ground cools faster at night than the water which retains its heat warming the air above at.
Gravity moves the air towards the water because water is lower than the land.
Answers
Answer:At night, the roles reverse. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes the low surface pressure to shift to over the ocean during the night and the high surface pressure to move over the land.

How do the molecules in your body affect the energy released in the cells?
Answers
Explanation:
When the chemical bonds of the glucose molecule are broken, energy is released. The cell is able to store that energy in the chemical bonds of a special molecule called adenosine triphosphate or ATP. The energy stored in ATP can be used by the cell to do various kinds of work.
These large polysaccharides contain many chemical bonds and therefore store a lot of chemical energy. When these molecules are broken down during metabolism, the energy in the chemical bonds is released and can be harnessed for cellular processes.

People with prediabetes have blood glucose levels higher than normal, but not high enough to be diagnosed with type 2 diabetes. Having prediabetes increases your risk for type 2 diabetes, heart disease, and stroke.
