Answer:
Explanation:
Two possible causes for the biggest mass extinction event in the history of our planet would be an asteroid impacting the planet and the massive volcanic activity. This mass extinction event is called the Permian-Triassic extinction. This helped many species emerge as survivors and thrive without the oppressive bigger species that died out. It hurt many species that were unable to survive the harsh conditions that resulted from everything that was happening to their habitats and food sources.

The diagram shows a process that takes place in certain organisms.
Which statement correctly identifies and describes the process taking place?
1- The process is cellular respiration in which chemical energy is being converted to light energy.
2- The process is cellular respiration in which light energy is being converted to chemical energy.
3- The process is photosynthesis in which light energy is being converted to chemical energy.
4- The process is photosynthesis in which chemical energy is being converted to light energy.
Answer:
I'm going to have to say 2
Explanation:
I'm not sure about photosynthesis because it's not making any glucose, or it doesnt show that in the diagram, but it is making oxygen which is a chemical reaction because it cant go back to carbon dioxide through the plant.
The process that takes place in certain organisms is photosynthesis in which light energy is being converted to chemical energy. Thus option 3 is correct.
what is photosynthesis ?The process in which sunlight energy is used by plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.
Photosynthesis occur in chloroplast which has its own DNA, genes and hence can synthesize their own proteins, photosynthestic Pigments responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.
Bacteria also have chlorophyll known as bacteriochlorophyll can absorb infrared rays, other pigments are Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.
plastids are found in the cytoplasm of eukaryotic photosynthetic organisms. They contain pigments and store nutrients. Plastids are of three types such as Leucoplast, Chromoplasts, Chloroplasts

A normal cell has a high concentration of potassium on the inside and a low concentration of potassium on the outside. Also, a normal cell has a low concentration of sodium on the inside and a high concentration on the outside. Yet, the net movement of potassium is into the cell and the net movement of sodium is out of the cell. What type of transport is involved?
Osmosis
Facilitated diffusion
Active transport
Diffusion
Answer:
Is there a higher concentration of potassium inside or outside the cell?
The sodium and chloride ion concentrations are lower inside the cell than outside, and the potassium concentration is greater inside the cell. These concentration differences for sodium and potassium are due to the action of a membrane active transport system which pumps sodium out of the cell and potassium into it.

In the lytic cycle, how does the virus cause
the host cell to die?
By taking over the bacterial cell and making it produce viral DNA
and protein.
By becoming part of the host DNA.
By damaging the cell membrane as it injects viral DNA into the
host celL.
Answer:
A
Explanation:
A virus, or phage, will go into a cell and inject instructions for it to start reproducing more viruses. Once the cell is full of viruses, they trigger the cell's 'self destruct' and burst out to go to other cells and rapidly reproduce exponintially.
which of the following statements is FALSE?
a. alleles are made when one original DNA strand experiences mutations that result in phenotypes that offer advantages
b. the DNA of two alleles must be almost identical. since the trait is the same. But the effect of the allele may be very different!
c. in humans, for every trait we can only have two alleles. but that trait can be controlled by many alleles. there are no limits on how many alleles can control a trait.
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
e. if humans were diploid we would only have one allele per trait
Helpppp pleaseee
Answer:
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
Explanation:
Being diploid means humans carry two sets of chromosomes. Since we have both dominant and recessive gene types, humans can mask the effect of recessive alleles since the dominant trait will be seen in the phenotype or genotype since it is a dominant gene. The effect of the recessive allele will show up only if both diploid genes are recessive.

In what aspect the enzyme is different from other catalysts ? help please
Answer:
Enzymes and catalysts both affect the rate of a reaction. In fact, all known enzymes are catalysts, but not all catalysts are enzymes. The difference between catalysts and enzymes is that enzymes are largely organic in nature and are bio-catalysts, while non-enzymatic catalysts can be inorganic compounds.

Explanation:
The graph below represents the effect of enzyme concentration on the reaction rate.
Based on this graph, what can you conclude about the relationship between enzyme concentration and the rate of starch chemical reaction? (ASK 1a1)(DOK1)
Question 4 options:
a. The reaction rate decreases as the enzyme concentration increases
b. The reaction rate increases as the enzyme concentration decreases
c. The reaction rate increases as the enzyme concentration increases
d. The reaction rate is indirectly proportional to the enzyme concentration
Answer:
C
Explanation:
Increasing enzyme concentration will speed up the rate of a reaction, as long as there is substrate available to bind to.
Rate of reaction is directly proportional to the enzyme and substrate concentration. Therefore, option (C) is correct.
What is enzyme- substrate complex ?
An enzyme-substrate complex is what happens when a substrate attaches to an enzyme's active site during a chemical process. Aspects including temperature, pH, co-factors, activators, and inhibitors can affect an enzyme's activity.
A substrate is placed into the active site of the enzyme, or the location where weak bonds can form between two molecules. An enzyme substrate complex is created, and the enzyme's pressures on the substrate cause it to react and turn into the reaction's intended product.
Therefore, option (C) is the correct option as long as there's enough substrate for enzyme to bind and convert to product.

Are eukaryotes more closely related to bacteria or to archaea? Explain.
Hello!
The Answer Is: Bacteria and Archaea are comprised exclusively of microorganisms; plants, mammals, and microorganisms such as fungi and protists are contained in the Eukarya. Because of their lack of a nucleus, the Bacteria and Archaea were grouped together and called Prokaryotes, but the Archaea are more closely connected to the Eukaryotes than to the Bacteria. The cell walls of bacteria contain a compound called peptidoglycan, while the cell walls of archaea do not. Archaea and bacteria also vary because the composition of the cell membranes of archaea is peculiar and does not contain the same lipids, or fats, present in other species' cell membranes.Thank you for asking this question!

The thallus of a mold consists of long, branched, threadlike filaments of cells called _________ that form a tangled mass called a
Answer:
Hyphae; mycelium.
Explanation:
Fungi can be defined as living microorganisms that are eukaryotic in nature and are able to reproduce using both means of reproduction i.e both asexually and sexually. Also, fungi do not have chlorophyll but are of great importance to the human world both scientifically and practically.
A thallus can be defined as the vegetative or bodily structure of fungi. Thus, the various forms of fungi are;
I. Yeast.
II. Mushroom.
III. Mold.
A mold is typically multicellular (has more than one cell) and filamentous in nature. The thallus of a mold consists of long, branched, threadlike filaments of cells called hyphae that form a tangled mass called a mycelium.
The thallus of a mold consists of long, branched, threadlike filaments of cells called Hyphae that form a tangled mass called a mycelium.
What are hyphae and mycelium in fungi?Hyphae are the tubular projections of multicellular fungi that form a filamentous network. Fungal hyphae release digestive enzymes in order to absorb nutrients from food sources.
mycelium, the mass of branched, tubular filaments of fungi. The mycelium makes up the thallus, or undifferentiated body, of a typical fungus.
