Which one is odd one out on the basis of respiration:
Amoeba, cockroach, earthworm, euglena
Answer:
Cockroach is you answer.
Explanation:
They do this by using a very efficient breathing system that uses air filled tubes, called trachea, to deliver oxygen directly to cells. Oxygen flows in as required into the tracheal system through valves on the insect, called spiracles. But, sometimes, they shut their spiracles and stop breathing.

Explanation:
discribe the passive transport movement of a substance down it's concentration gradient through a protein channel embedded in the cell membrane
Answer:
The passive transport of a substance by its concentration gradient through a protein channel is called facilitated diffusion.
Explanation:
Facilitated diffusion is a type of passive transport through the membrane, which involves the use of integral proteins called protein channels or transport proteins, and moves substances unable to cross the membrane by simple diffusion.
An example of facilitated diffusion through protein channels is the ion channel. Ions, being electrically charged particles, cannot pass through the plasma membrane. A protein channel -which crosses the whole thickness of the membrane- constitutes a space where ions can move depending on their concentration gradient.
In facilitated diffusion, both protein channels and transport proteins do not require energy, so it is a transmembrane passive transport process.
In Hawaii, new land forms when lava erupts from Kīlauea volcano and hardens. The new land is without any living things. The first organisms to populate the surface of that new land are known as species. With time, a series of changes called succession occur on the new land through which it becomes colonized by a variety of organisms.
Answer:
Primary succession
Explanation:
The new landforms that are devoid of any vegetation have barren and rocky environment are colonized by the first plant species like grass and moss is called as primary succession which changes with time and occurs on new lands that not colonized yet and later on gets colonized a variety of organisms.how do organisms generate energy when oxygen is ot available

The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.
They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).
The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.
The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.

Analyze the diagram below. Which of the terms best describes it?
Answer:
disaccharides
Explanation:
they are formed by linking 2 monosaccharides through condensation
monosaccharides are simple sugars or glucose
Disaccharides are those types of carbohydrates that, when hydrolyzed by acids or enzymes, produce two molecules of monosaccharides that may or may not be identical. Thus, option A is correct.
What is important in formation of disaccharides?Mono- and disaccharides, sometimes known as sugars, make up a significant portion of the carbohydrates included in food.
Disaccharides function similarly to other carbohydrates as a source of energy for the body.
When we consume foods containing disaccharides, our systems convert them into monosaccharides, or simple sugars, for absorption in the small intestine.
This condensation process is also referred to as a dehydration reaction, since a water molecule is released during this process.
Therefore, disaccharide is formed from monomeric subunits.

What is electronegativity?The term "electronegativity" describes how attracted an atom is to the bonding electrons in molecules as opposed to other atoms.
American chemist Linus Pauling developed a set of dimensionless variables known as electronegativity values that vary from a little under one for alkali metals to a maximum of four for fluorine.
Electropositive elements are those that are on the left of the periodic table and have low electronegativities. We shall use the key attribute of the order of electronegativities F > O > N > C to explain the chemical properties of organic molecules.

Which would have most likely stopped Mendel from finding a pattern in his results?
O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring
Answer:
A. If seed shape did not have a clearly recessive form
Explanation:
To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.
For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.
Answer:
A. If seed shape did not have a clearly recessive form.

In one plant species petal color follows INCOMPLETE DOMINANCE. If there
are alleles for both red and white plants, what would a heterozygous plant's
phenotype be?
Red
Pink
White
Red and White
Answer:
Pink
Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other. The resulting phenotype of the heterozygote is intermediate between the two alleles. That means the flowers would be pink.
Red - no, this would be true if red was dominant to white
Pink - yes, this is an intermediate phenotype
White - no, this would be true if white was dominant over red.
Red and White - no, this would be true if the alleles were co-dominant and both equally but independently expressed.
Why does evolutionary theory absolutely require the earth to be very
old?
Answer:
Mainly because Evolution takes millions and millions of years to happen.
Explanation:
Evolutionary theory require earth to be very old because the process of evolution takes millions of year to happen.
What do you mean by evolution ?Evolution is the process through which a population of organisms evolves as new generations replace ancestors. Individual species do not evolve; rather, communities of organisms do.
Natural selection processes like as environmental change, predation, or human disturbance create evolutionary adaptations, and these processes must continue and grow widespread for the change to remain and accumulate. That happens less frequently and slowly than you may expect.
Scientists have determined that Earth is 4.54 billion years old, with a 50 million year error, by dating the rocks in its ever-changing crust as well as those in Earth's neighbors, including the moon and passing meteorites.
Therefore, the Earth needs to be very old for evolutionary theory to be true.
