What type of reproduction involves forming offspring from two
parents?
a Asexual
b Sexual
C Mitosis
int?
d Replication
Answer:
Sexual
Explanation:
Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Hope it helps
Answer: Sexual, I believe.
Explanation:
If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.

Which two viral characteristics provide evidence to support the
argument that viruses are more similar to living components than to
nonliving components of an ecosystem?
Living Characteristics of Viruses Nonliving Characteristics of Viruses They reproduce at a fantastic rate but only in living host cells. They can mutate. They are acellular that is they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.
Which of the following is TRUE about sedimentary rock?
A. does not contain layers
B. May contain fossils
C. the hardest of the rock types
Answer:
B
Explanation:
Sedimentary rock is layered. That makes A wrong, but it leads to another observation.
Things can die and think sink to the bottom of an ocean or sea or river or lake bed which over time changes. So you might find fossils which is the answer.
C is incorrect because there are much harder substances than sedimentary rock.
Answer:
B.May contain fossil.
Explanation:
These rocks are formed with the deposition of materials broken down from pre-existing rocks, followed by compaction and cementation
why are vitamins important to enzymes and what this relationship is called?
The activity of some enzymes requires vitamins. This is because vitamin derivatives contribute to the biochemical mechanisms of these enzymes. These vitamin derivatives belong to a class of molecules known as cofactors, which are organic molecules (called coenzymes) or metallic ions, that assist in the catalytic activity of an enzyme.
Q.2. Describe the different phases of meiotic prophase – I. Mention the chromosomal events during each stage.
Prophase-I occurs over a long duration and involves several complicated changes in meiotic cell division. It is important because genetic recombineiion and variation in sexually reproducing organism occurs due to the events of this phase.
EXPLANATION:❈ Leptotene —
➥ The chromatin network opens out and threads become clear.
➥ The chromosomes are thin, slender and long.
➥ Chromosome number is diploid.
❈ Zygotene —
➥ Corresponding chromosomes become intimately associated.
➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.
➥ The chromosomes become shorter and thicker.
❈ Pachytene or Pachynema —
➥ The synaptic chromosomes become very intimately associated.
➥ The pair of chromosomes becomes short and thick.
➥ Crossing over occurs at this stage. Chiasmata are clearly seen.
❈ Diplotene —
➥ Homologous chromosomes start separating from one another.
➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.
➥ Chromosomes start separating out but the separation is not complete.
➥ Nuclear membrane and nucleolus start disappearing.
❈ Diakinesis —
➥ The bivalents condense further and get randomly distributed.
➥ The separation of paired chromosomes is almost complete.
➥ Terminalisation of chiasmata is almost complete.
➥ Nuclear membrane and nucleolus disappear.

Globalization of the economy is increasing because of which of these
factors?
A. Agreements limiting immigration
B. Advances in internet technology
C. A decrease in demand for resources
D. Treaties limiting international trade
Answer:
Explanation:
B. Advances in internet technology - it allows ppl to order stuff from all over the world.
The globalization of the economy is increasing due to the reduction in the demand for resources. So, the correct option is C.
What is Globalization?Globalization is defined as the process by which people and goods move easily across borders which is an economic concept which is the integration of markets, trade and investment with the aim of slowing the flow of products and services between nations where there are some constraints.
The effect of globalization is that it promotes increased interaction between different regions and populations around the world. The globalization of the economy is increasing due to the reduction in the demand for resources.
There are three types of globalization.
Economic globalizationPolitical globalizationCultural globalizationTherefore, the correct option is C.

How does bursting of animal cells take place
Answer:
Swelling and bursting of cells is also known as lysing. This happens when the concentration of solutes inside the cell is greater than the concentration of solutes outside the cell. It has to do with diffusion and osmosis. A high solute concentration relates to a lower water concentration. Since molecules like to diffuse from areas of high concentration to areas of low concentration, water will rush into the cell where the water concentration is lower causing it to swell and lyse.
Explanation:
What is the independent variable of great white sharks travelling distance?
Answer:
Each year, great white sharks migrate over long distances from their feeding grounds off the central California coast to other feeding grounds far away in the Pacific Ocean. ... That's one reason they migrate from one feeding ground to another, to take advantage of the seasonal bounty.
It's though that a shark can travel up to 50 miles in one day. While we cannot know this for certain as sharks have never been tracked this way, 50 miles is a good estimate

“Explain how chemical energy for use in the cell is generated by electron transport and chemiosmosis”
PLEASE HELP!!
*50 points to whoever can answer that question and draw a flowchart, thank you*
Answer: The ETC is the last part of cellular respiration. In the first steps of cellular respiration (glycolysis and Krebs cylce), electrons are freed from glucose derived molecules. In the ETC the electrons are passed on through a series of proteins in the inner membrane of the mitochondria. The electrons in a sense 'flow' to lower energy levels (see image), they lose energy in the process.
Energy produced by H+ travelling via ATP synthase and down a concentration gradient is used by chemiosmosis. ADP is phosphorylated with this energy to create ATP.
What is Chemiosmosis?Chemiosmosis is the passage of ions along their electrochemical gradient through a semipermeable transmembrane domain structure. Adenosine triphosphate is created when hydrogen ions pass a membrane during photosynthesis or cellular respiration. This is a significant example.
The process of ions (often H+ ions, commonly referred to as protons) diffusing across a membrane that is selectively permeable is known as chemiosmosis. Chemiosmosis produces a concentration gradient of a diffusing ion from across membrane, similar to osmosis. Potential energy that can perform work is present in concentration gradients.
Thus, energy produced by H+ travelling via ATP synthase and down a concentration gradient is used by chemiosmosis. ADP is phosphorylated with this energy to create ATP.

Explanation:
humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacteria than once killed how does the theory of evolution explain this antibiotic mutated the bacteria which allowed resistance develop
Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.
