Answer:
Large groups of the same type of cell, all working together for one purpose.
Explanation:
Human tissues are the group of cells that work together to perform a specific function. In tissues, similar type of cells combine together for performing similar function. The cells in tissue are same type means same size and structure. When a group of tissue combine together, it forms organ. These tissue can be broken down into simpler substances which are the cells that are considered as the basic unit of life.
Which of the following describes a scientific theory, such as evolutionary theory? (Check all that apply).
A. When a scientific theory is proven, it becomes a scientific law.
B. It is an explanation for a wide variety of natural phenomena.
C. It is plausible explanation for many natural phenomena that has not yet been fully tested.
D. Scientific theories are the most certain knowledge that can be developed in science.
E. Numerous studies, which have all tested the theory but in different ways, have all converged on the same explanation.
F. There is ample evidence supporting the explanation.
Answer:
b
Explanation:
Evolutionary theory highlights the adaptive value of within-species variability. Optimal biological and behavioral strategies differ depending on the nature of the environmental context as well as the characteristics of the organism such as age, sex, health, or physical size.

Which of the following is an accurate statement about pathogens? (2 points)
Infection and disease are caused by pathogens living in infectious agents found in the environment.
Pathogens, which cause infection and disease, are the most abundant organisms in the environment.
Most organisms in the environment are harmless, except for pathogens, which can cause disease.
The environment is rich in infectious agents that transmit disease through pathogens.
Answer:
I believe it is d
Explanation:
The answer is Most organisms in the environment are harmless, except for pathogens, which can cause disease.
The oldest and broadest pathogens are any organism or pathogen that can cause disease. Pathogens are sometimes called infectious pathogens or simply bacteria. The term pathogen came into use in the 1880s.
Pathogens are usually defined as microorganisms that cause or can cause disease. Pathogens are defined as microorganisms that can harm the host.
Various microorganisms can cause illness. Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms. Some common pathogens in each group are listed in the column on the right.

what is likely to happen to a water molecule entering lamella in the process of photosynthesis
Answer: Explanation: The granum is a part of the chloroplast. The chloroplast contains the chlorophyll pigment and it is necessary for the trapping of the energy present in the sunlight. As a result of this the photolysis of water takes place and hence water is broken down from water molecule to proton and oxygen

Which two characteristics describe the most stable ecosystem on Earth?
a. They are near the poles
b they are near the equator.
c. They have high biodiversity
d they have few seed plants
Answer:
They have high biodiversity
High at the equator
Explanation:
This is because a stable ecosystem is the one that occur at equilibrium and have the ability to resist any form of resilience or disturbance and still grow fast. A stable ecosystem have high biodiversity because that are comprises of different plants and animals that are able to live and survive. Species diversity are more at the equator than at than at the poles.

If an organism's body cells have 12 chromosomes, how many chromosomes will sex cells have? Explain.
Answer:
6 chromosomes
Explanation:
Answer:
The gametes or sex cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes.
Explanation:
The diploid organism has all chromosomes in pairs, one chromosome inherited from male parent & another chromosome in the pair is inherited from the female parent. If an organism has 12 chromosomes, it has 6 different types of chromosomes, differing from one another in length, the position of centromeres and genes present on these. Six different types of chromosomes constitute a haploid set of chromosomes. Two chromosomes of the same type are called homologous chromosomes and these constitute a homologous pair. The cells producing sex cells or gametes undergo meiosis (reduction division) so that each gamete contains only one chromosome of a homologous pair. The gametes are haploid, having half the number of cells as compared to somatic cells.

The table shows data about abiotic factors of streams in two different watersheds.
In general, a stream with a lower temperature and more neutral pH tends to be healthier. Based on these
criteria, which watershed contains the healthier stream?
Select one:
Watershed 2
Both streams are equally healthy.
There is not enough data provided to answer the question.
Watershed 1
Answer: b
Explanation:
Based on these criteria, the watershed that contains the healthier stream is, that both streams are equally healthy. The correct option is B.
What are abiotic factors?An abiotic factor is a non-living component of an ecosystem that influences its surroundings. Temperature, light, and water are all components of the terrestrial environment.
Abiotic elements in a marine ecosystem include salinity and ocean currents. Abiotic and biotic forces interact to form a distinct ecosystem. Abiotic influences are found in all non-living components of an ecosystem.
They are often made up of both physical and chemical components. Abiotic factors are nonliving components of an ecosystem that influence the environment. Temperature, light, and water are among the examples. Abiotic elements in a marine ecosystem include salinity and ocean currents.
Therefore, the correct option is B. Both streams are equally healthy.

Explain how the flow of energy is linked to entropy and how the law of conservation of matter applies to the carbon cycle
The first law of thermodynamics is equivalent to the law of conservation of energy: energy cannot be created or destroyed; the total amount of energy in the Universe is fixed. Energy can be transformed from one form to another or transferred from one place to another but the total energy must remain unchanged.

Which of the following is not a difference between photosynthesis and cellular respiration?
Answer: D
Explanation: They both play an important role in the carbon cycle. Photosynthesis removed CO2 from the atmosphere while cellular respiration causes the release of CO2 into the atmosphere.
The others are major differences
Photosynthesis has as its products Starch and O2 while those of cellular respiration are water , CO2 and energy.
The materials needed for photosynthesis are water and CO2 while those for cellular respiration are starch and O2
Photosynthesis occurs in chloroplast while respiration takes place in mitochondria .
Thus the only non- difference is D.
