Answers

Answer 1
They are both eukaryotic
Answer 2

Following statements are true:

Plant cells are eukaryotic

Animal cells are eukaryotic

What are eukaryotic cells?

Eukaryotic cells are characterized by the presence of a true nucleus, which is a membrane-bound structure that contains the cell's genetic material. They also typically have other membrane-bound organelles, such as mitochondria, Golgi apparatus, and endoplasmic reticulum, which perform specific functions within the cell.

In contrast, prokaryotic cells are characterized by the absence of a true nucleus and other membrane-bound organelles. Instead, they have a single, circular chromosome that is not enclosed in a nucleus, and they have other simple cell structures that perform functions within the cell.

Both plant cells and animal cells are eukaryotic cells, while prokaryotic cells are found in bacteria and other single-celled organisms. Therefore, the statements "Animal cells are prokaryotic" and "Plant cells are prokaryotic" are not true, while the statements "Plant cells are eukaryotic" and "Animal cells are eukaryotic" are true.

Answer:

bacteria are found everywhere even in hot springs. Bacteria are different from other organisms because they don't have membranes bound organelles .they replicates to produce

Explanation:

Answer and Explanation:What are some examples of suitable environments for bacteria?

Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.

How might bacteria avoid dying if an environment is not suitable?

Many types of bacteria, if environmental conditions become unfavourable (lack of water, increase in temperature, etc), will go into a sort of dormant state, called an Endospore.

How are bacterial cells different from plant and animal cells?

Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or Golgi apparatus.

Describe how bacteria reproduce. How can bacteria acquire new characteristics?

Bacteria reproduce through a process called binary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell.

In seals, the gene for the length of whiskers has two alleles. The dominant allele (L) codes long whiskers & the recessive allele (l) codes for short whiskers. If one parent seal is purebred long-whiskered and the other is a hybrid, what percent of offspring would have long whiskers?

Answers

Probably around 75% because one parent is a hybrid so it is half long and short and th other parent is long
It would most likely be around 75 becuase assuming that 1 seals genes is worth 50 percent and the others is also worth 50 percent than you have a 50 and 25 percent chance of long whiskers

how does a field mouses adaptaions help it survive (paragraph please 5 sentences)

Answers

Field mice have developed a number of adaptations that enable them to survive in their environment. One of the most important adaptations is their ability to burrow into the ground to create nests and escape from predators. This not only provide shelter, but also allows them to regulate their body temperature. Another important adaptation is their keen sense of hearing, which allows them to detect predators and other potential threats. They also have excellent vision, and sense of smell, which they used to locate food and avoid danger. Finally, field mice, have a quick reproductive cycle, which enables them to rapidly increase their population and avoid extinction. Together these adaptation to get field mice, a survival advantage in their habitat.
Hope this helps! :D
A field mouse is a small rodent that is found in fields, meadows, and hedgerows all over the world. It has adapted to life in the wild in several ways to ensure its survival. For example, during the winter months, it builds a nest in the ground, typically underground, to help protect it from the harsh elements, and it hibernates to conserve energy. In the spring and summer, it becomes more active, foraging for food and building a new nest.

The field mouse has many predators, such as owls, snakes, and foxes, so it has adapted by being very cautious and alert at all times. It's also evolved to have good hearing, sight, and smell to help it detect predators and potentially dangerous situations.

The field mouse's diet consists of seeds, grains, and insects. They forage mainly at night to avoid predators and have evolved to have a great sense of smell to locate food.

Overall, the field mouse's adaptability and cautiousness have allowed it to survive and thrive in the wild.

D) Green, and yellow light by chlorophyl a, chlorophyl B, and carotene

Answers

Answer:

B) Violet and blue light by chlorophyl a and orange, and red light by chlorophyl B

Explanation:

Chlorophyll is the pigment present in green plants which is used in the process of photosynthesis by trapping solar energy for use. Chlorophyll comprises of two types namely: Chlorophyll A and Chlorophyll B

Chlorophyll A is known to absorb light in the blue-violet region while chlorophyll B absorbs light in red-blue region. These pigments however don’t absorb green light but they instead reflect it. This makes option C and D invalid. The closest option in their properties is however B.

Answers

Answer:

I believe the answer is A - Lions show their cubs how to hunt for prey. Hereidty is having the same genetics are your family member(s).

When lions show their cubs how to hunt for prey, it is not an example of heredity. Thus, the correct option is option A.

Heredity is the process by which features or qualities are passed down through genes from one generation (parent) to the next (offspring). Sexual reproduction is a fairly clear example of heredity. This is so because there is a lot of variety in the inherited traits during this phase.

Errors in DNA copying are the cause of the variance. Variation is significant because it supports heredity and aids in evolution. Gene mutations, how genes interact with the environment, and different genetic material combinations all contribute to variation. Keep in mind that variation can also be produced asexually. These differences, however, are barely perceptible.

2. What is carbon footprint?
3. What is the difference between finite and infinite?
4. How does using a fan lowers the greenhouse gas emissions?
5. What is mitigating?
6. How can sweeping minimizes noise pollution?
7. How does planting can conserve our natural resources?​

Answers

Answer:

Explanation:

1) Hanging clothes to dry reduces electricity use and greenhouse gas emissions and makes clothes last longer.

2) The carbon footprint serves as an indicator to compare the amount of greenhouse gases emitted over the entire life cycle from the production of a good or service along the supply chain to its final consumption

3) The word 'Finite' itself describes that it is countable, and the word 'Infinite' means it is not finite or uncountable.

Answer:

Explanation:

1.) Using hanging clothes instead of using any machine(dryer) reduces the emission of gases and uses natural ways (sunlight, wind) to dry them up.

2.) Carbon footprint can be defined as the amount of greenhouse gases especially carbon dioxide (CO2) and methane emissions, that relate to daily human activities.

3.) If the no. of elements are countable then they are said to be finite, while if the no. of elements are uncountable then they are said to be infinite.

4.) Fans help to evaporate moisture from the skin, providing a cooling effect as it creates breezes instead of cooling it, while

Air conditioners remove heat from the air by using energy-intensive refrigeration cycles,

Thus fan helps to reduce greenhouse gas emissions.

5.) Mitigating refers to the act of reducing or minimizing the negative impacts of a particular issue or problem.

Suppose you were asked to research information about a potentially dangerous synthetic food product. How would you evaluate the credibility of the sources you found?

Answers

Look at the studies cited in the source and the credentials of the scientists, if there are no studies cited it’s not a good source. Look at whether the ending of the link is .gov/.edu, any other ending is less credible. Check and see if the FDA has approved these food products or denied them. And finally look at the author and the authors credentials.
A good way to tell whether or not a website is reliable is the ending of the link (.com, .net, etc). Websites with .gov are more reliable because it is a government site. Websites with .com or .net can be reliable however it is always good to check the author of the website to make sure they know what they're talking about.

The domestic dog, Canis lupus familiaris, is an example of an organism that might have siblings with dissimilar features.

What is the organism?

Dogs are a very diverse species, with a wide range of physical and behavioral characteristics. Because they have the same parents, siblings have genetic makeup that is similar, but different gene combinations can result in significant variances in characteristics like coat color, size, and temperament.

The puppies' coats might be any color between black, white, and gray if one parent has a white coat and the other has a black coat, for example. Additionally, environmental factors and genetic abnormalities might cause attribute discrepancies between siblings.

predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents

Answers

A pedigree chart is used to track inherited traits through generations.

A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.

Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.
