Answer:

We cannot conclude anything without having more data.

Explanation:

All the statement says it that the birds have different types of beaks. There is no mention of information that the beak difference brings advantage or not. If the question were to say the heavy beaks survive more, then the answer would be those birds have an advantage- because it does not, the answer is we need more data

Answer:

Explanation:

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance

Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself

Centrioles play a role in organizing microtubules that serve as the cell's skeletal system. They help determine the locations of the nucleus and other organelles within the cell.

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.

Answer: the tundra is important to protect is that it serves as a habitat for migratory populations, like waterfowl, shorebirds, caribou and several bear species. It is home to endangered animals such as the Arctic Fox, Polar Bear, Grizzly Bear, Caribou, and Musk Ox.

Explanation:

Genetic drift, gene flow, mutations, and natural selection are responsible for the change in the gene pool over time. Example of genetic drift: a population of rabbits with alleles B and b, both alleles are present in equal frequencies p = 0.5 and q = 0.5 if 10 parents reproduce the probability of having an offspring with alleles B or b is 0.5; however, by chance, a slight difference in the offspring allele frequency might occur due to random sampling. As a result, in the next generation, the allele frequencies will change slightly to new frequencies by chance to become p = 0.4 and q = 0.6. in the following generations, the random sampling of alleles continues and the change in allele frequency will be greatly different from the initial 0.5 frequency due to genetic drift. Even though genetic drifting is one of the factors that participate in the evolutionary process of the genetic pool by increasing or decreasing a certain allele’s frequency, however, it does not influence the adaptation of individuals to the environment since the affected genes may be harmful or beneficial genes.

Answer:

Carbohydrates

Explanation:

Carbohydrates are a group of macromolecules that are a vital energy source for the cell, provide structural support to many organisms, and can be found on the surface of the cell as receptors or for cell recognition.

Answer:

vellus

Explanation:

Think recessive phenotypes as paper and dominant phenotypes as teared paper. Once paper is teared, it can't be fixed. Not even tape. It'll just leave that mess exposed. Same with dominant phenotypes. It just takes one dominant trait to change the looks of future offspring.

If you don't tear the paper, everything is fine. Same with recessive phenotypes. As long as there's no contact with any dominant phenotypes, the looks of future offspring will change.

Answer:

Decrease the pumping of NADPH across the thylakoid membrane

Decrease of flow of electrons from photosystem II to photosystem I

Explanation:

Thylakoids are defined as a membrane-bound compartments located inside the chloroplasts and the cyanobacteria. Here, light-dependent reactions of photosynthesis occurs.

To block the photosynthesis process, the herbicides pushes the dichlorophenyl dimethylurea to block the electron flow through the photosynthesis II and it reduces the flow of electrons from photosystem II to photosystem I. It also decreases pumping of the NADPH across the thylakoid membrane.

Explanation:

Answer:

(a)The strength of natural fibers is very less as compared to synthetic fibers.  Natural fibers are heavy in weight.  Natural fibers can be damaged by moths and other insects.  These fibers are not wrinkle-free.  These fibers are not long lasting and hence not durable.

(b)  Cellulose is termed as polymer because it is made up of many monomer units.

(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.

(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.

(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.

(f) When the piece of cotton is burnt then it burns completely and produces no odour or smell. When nylon is burnt, It completely burns and produces burning paper like odour. When nylon is burnt then the nylon is completely shrink and starts to melt first and then produces odour during the time of burning

In the atom, the arrow 1 depicts the proton. The arrow 2 depicts the neutrons, and the arrow 3 depicts the electrons. All three of these are subatomic particles.

An atom is the fundamental structural unit of matter. It consists of protons, neutrons, and electrons. Electrons are negatively charged particles that are present outermost shell of the atom, while protons are positively charged particles that make up the core of the atom. The neutron doesn't have any charge.

Both neutrons and protons make up the core of an atom, while electrons revolve around them. A neutral atom has equal numbers of protons and electrons. Example: the sodium atom.

Hence, the atom showing arrow 1 is a proton, arrow 2 is a neutron, and arrow 3 is an electron.

Answer:

DNA replication involves synthesis of DNA molecules, while transcription is a process that involves synthesis of RNA molecules. In both processes, DNA acts as template and provides information for synthesis of new daughter DNA or RNA strand.

Explanation:

the process green plant taking food from sun light is called photosynthetis

Answer:

Photosynthesis is a process through which plants and other organisms transform light energy into chemical energy, which is then released to power the organism's metabolic processes through cellular respiration.

all you're trying to do is create a histogram of what has happened in the past and what could happen in the future.

Explanation:

for example and AD you feel the first little bar because it's not more than a billion and its last therefore it would be the zero billion

and then for 1850 you feel to bars because they had 1 billion people so therefore you feel the 0 billion and the 1 billion part

Answer:

Partially separate circuits for gas exchange and systemic delivery of blood.

Explanation:

Adult amphibians have separate circuits for gas exchange and systemic delivery of blood. Fishes usually breathe through gills  and very few have nostrils. The fishes can breathe underwater with the help of their gills.
