Plants absorb sunlight through Photosynthesis. Which characteristic of life is this an
example of?
A. Obtains and uses energy
B. Responds to stimuli
C. Grows and develops
D. Homeostasis
Answer:
A. Obtains and uses energy
The characteristic of life shown here is plants obtain and use energy.
What is photosynthesis?By using the energy from sunlight, plants, some bacteria, and some protozoa make sugar, which cellular respiration then transforms into ATP, the "fuel" that all living things use. The green pigment chlorophyll is responsible for the transformation of inefficient solar energy into useful chemical energy. The photosynthetic process makes use of water and emits the oxygen that is vitally necessary for our continued existence.The overall reaction of photosynthesis is:6H₂O + 6CO₂ + light energy → C₆H₁₂O₆+ 6O₂

Which statement best describes how a catalyst can speed up a chemical reaction? The catalyst decreases the reaction energy needed. The catalyst increases the concentration of products. The catalyst binds to enzymes to release substrates. The catalyst increases the concentration of reactants.
Answer:
The catalyst decreases the reaction energy needed.
Explanation:
The catalyst speeds up chemical reactions by decreasing the amount of activation energy/reaction energy needed in the reaction.
Compared to reactions without catalysts, they are much faster because there is less activation energy needed.
Catalyst is any substance that causes or increases the rate of a chemical reaction without itself being consumed For example - enzymes are biocatalysts.
The catalyst can speed up a chemical reaction by reducing the activation energy or by changing the reaction mechanism.
The minimum amount of extra energy required by a reacting molecule to get converted into the product is defined as activation energy.
So, the correct answer is The catalyst decreases the reaction energy needed.
Other options-
The catalyst increases the concentration of products- incorrect. Catalysts do not affect the equilibrium concentrations of products or reactants. The catalyst binds to enzymes to release substrates- incorrect. The catalyst binds to the substrate and converts the substrate into products.The catalyst increases the concentration of reactants- incorrect.

The curve on the right shows the population five years later. What has happened to this population? (Available answers are in photo) Will mark best answer BRAINLIEST
Explanation:
DIRECTIONAL SELECTION!!!!!!!!!!!!!!!!!!
The population of penguins has gone through the directional selection.
What is directional selection?It is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes.
This causes the allele frequency to shift over time in the direction of that extreme advantageous phenotype.
How these two graphs shows directional selection?On each graph, the X-axis variable is the type of phenotypic trait (here height) and on the y- axis variable is the number of penguins.
Left graph shows the population before directional selection and right graph shows the population after directional selection.
Here height of the penguins reduces and favored over time due to directional selection.

The image shows a paramecium and a bacterium. One of these organisms is very good at rapidly adapting to environmental changes because it has the ability to take in stray genetic information from the environment. Which structure allows the organism to do this?
Answer:
The bacteria forms new kind of cells to adapt to a new environment. This adaptation is under tight genetic control, involving the expression of multiple genes.
the bacteria need to adjust their enzyme levels in order to quickly benefit from the nutrient mix that is currently available in the surrounding.
If the living environment undergoes a sudden change, the bacterium's own production of proteins has to fulfill these changes in an effective way.

What do you mean by cellulose?Cellulose is an organic compound with the formula ₙ, a polysaccharide consisting of a linear chain of several hundred to many thousands of β linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.
Moreover, cellulose, a tough, fibrous, and water-insoluble polysaccharide, plays an integral role in keeping the structure of plant cell walls stable. Cellulose chains are arranged in microfibrils or bundles of polysaccharide that are arranged in fibrils (bundles of microfibrils), which in turn make up the plant cell wall.
Hence, cellulose is an insoluble dietary fibre consisting of glucose polymers present in all cell walls of plants.

What is a similarity between a tulip and a crocodile? A function of both of their outer coverings is to reduce water loss. In both the tulip and crocodile the male reproductive organ is the testes. The tulip and crocodile both have internal skeletons that support them. The outer coverings of the tulip and crocodile both protect the organism.
Answer:
A function of both of their outer coverings is to reduce water loss
Explanation:
Crocodile and Tulips are both distinct species of organisms. Crocodile belongs to Kingdom Animalia while Tulips belong to Kingdom Plantae. However, despite their elaborate differences, they do have one feature in common, which is the function their outer covering performs.
Tulips are temperate plants I.e. like cold regions, hence, their outer covering functions to prevent excessive loss of water. On the other hand, the scaly skin of the crocodiles help them against water loss. This is common between the two different species.
