Puffins live in the Arctic. Penguins live in the Antarctic. Suggest reasons why puffins and penguins are both similar and different
Answer:
Puffins are not actually penguins! They are birds that look similar, but are not the same species. Puffins belong to a family of birds called Alcidae, while penguins belong to the family Spheniscidae; their wings evolved to support different functions.

What does this pyramid tell us about the population?
The answer is A. The population is growing.
The pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.
What is population?Population is defined as the quantity or population of people living somewhere who are a particular social, cultural, economical, ethnic, or racial category. Making decisions can be aided by knowledge of how population parameters, such as size, regional distribution, age structure, or birth and death rates, vary over time.
The pyramid is used to show the growth in population of a country or population of the city. In the pyramid the growth of population is equal in both male and female population. The pyramid shows that the population of older generation is less than the population of younger generation peoples.
Thus, the pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.

How do you think specific traits help organisms access or utilize resources more efficiently?
Answer:
Individuals with adaptive traits, traits that give them some advantage are more likely to survive and reproduce. Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.
here are some example
Adaptatio ——A trait that improves an organism's ability to survive and reproduce in an environment
Fitness——The ability of an organism to survive and reproduce
Artificial selection——Selective breeding of organisms to promote the appearance of desirable traits in offspring
Explanation:
Summarize taste considerations.
The word taste, or gustation, to give its full name, refers to what is detected by the taste cells, located on the front and back of the tongue and on the sides, back and roof of the mouth. These receptor cells, or taste buds, bind with molecules from the food or drink being consumed and send signals to the brain.

How much of a chromosome is copied into rna during transcription?
Answer: How many genes are copied during transcription?
The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. If the gene encodes a protein, the transcription produces messenger RNA (mRNA); the mRNA, in turn, serves as a template for the protein's synthesis through translation.

Identify Organelles in an Animal Cell
Answer:
A- Nucleus
B- Lysosome
C- Ribosomes
D - Centrioles
Explanation:
Got it right on edge2021
The cell organelles in an animal cell are Label A: Nucleus, Label B: Lysosome Label C: Ribosomes, and Label D: Centrioles.
Digestive enzymes found in lysosomes break down waste products from cells as well as foreign objects. They are essential for the recycling of cellular parts and preserving cellular homeostasis.
Ribosomes can be found either bound to the endoplasmic reticulum or floating freely in the cytoplasm. They interpret the messenger RNA (mRNA)-encoded genetic instructions and produce proteins in accordance.
Centrioles are essential for the development of the mitotic spindle, which helps separate the chromosomes during cell division.
Additionally, they play a role in the development of cilia and flagella, which are critical for some cell types' ability to move and perform sensory tasks.
Thus, the answers are nucleus, lysosome, ribosome, and centriole respectively.

The animal-like parasite plasmodium causes the disease
Answer:
Malaria is the answer
Explanation:
The animal-like parasite plasmodium causes diseases like malaria.
What is malaria?A parasite that frequently infects a particular species of mosquito that feeds on people can result in a serious and occasionally fatal disease known as malaria.
An obligatory parasite of insects and vertebrates, Plasmodium is a genus of unicellular eukaryotes. The parasite Plasmodium, which causes malaria, is spread via the bite of an infected mosquito.
Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Through the bites of female Anopheles mosquitoes carrying the parasites that cause malaria, people can contract this potentially fatal illness. It can be avoided and treated.
Therefore, malaria is brought on by the parasite plasmodium, which resembles an animal.

How much dna is in each nucleus of each cell
Answer: Look below =3
Explanation: That makes a total of 6 billion base pairs of DNA per cell. Because each base pair is around 0.34 nanometers long (a nanometer is one-billionth of a meter), each diploid cell therefore contains about 2 meters of DNA [(0.34 × 10-9) × (6 × 109)].
Each cell has 1 DNA. When it is mitosis, a piece of DNA breaks down into thing called chromosome.

what happans to DNA inside the necleus before meiosis begins?
Answer:
Before mitosis begins, the cell has already made new copies of each of its chromosomes. However, these new copies remain attached to the original chromosome. A dividing cell must be able to pull the copied chromosomes apart from the original copies, which is how the DNA is evenly divided when one cell splits into two.

what would happen if the igneous rock was first exposed to energy from the sun
Answer:
If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock. Consider how granite changes form. Granite is an igneous rock that forms when magma cools relatively slowly underground
Explanation:
Answer:
An igneous rock can change under pressure to metamorphic. A igneous rock can turn into another igneous rock by melting and solidifying, it can turn into a sedimentary rock by getting weathered then recemented, or it can turn into a metamorphic rock by being subjected to great heat and pressure
Explanation:
If a cell has 14 chromosomes, how many chromosomes will each daughter cell have after mitosis and cytokinesis?
Why is this important?
Answer: After mitiosis, each daughter cell will also have 12 chromosomes. Cytokinesis is just the last stage of telophase, where the cell completely forms the two daughter cells. Telophase does not form chromosomes.
Explanation:
If a cell has 14 chromosomes, there are 14 chromosomes in each daughter cell.
What happens in Mitosis?There are four stages of mitosis: prophase, metaphase, anaphase and telophase.
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres.
2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)
3) Anaphase: sister chromatids are pulled to opposite poles of the cell
4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin.
If a cell has 14 chromosomes, there are 14 chromosomes in each daughter cell.
