How is an ectotherm most likely to maintain homeostasis during hot weather?
Answer:
The correct answer is - by burrying underground.
Explanation:
In the ecthermal animals who are also known as the cold-blooded animals. These animals change the heat from the environment and exchange through various ways if the weather is too hot.
Evaporating by tounge, moving to a shady area like under a tree or rocks, burrying the ground for the cooling down their body are few of the ways they maintain their homeostasis during hot weather.

Propose what happens to sodium and potassium ions during hyperpolarization.
Answer:
En biología, la hiperpolarización es cualquier cambio en el potencial de membrana de la célula, que hace que esté más polarizada. Es decir, la hiperpolarización es un incremento en el valor absoluto del potencial de membrana de la célula.
During hyperpolarization, sodium ions are pumped out of the cell and potassium ions are pumped into the cell, leading to an overall increase in the negative charge within the cell.
What is hyperpolarization?Hyperpolarization is a process that occurs in cells, particularly in neurons (nerve cells). It is characterized by an increase in the negative charge within the cell, which results from the movement of ions across the cell membrane. During hyperpolarization, sodium ions are pumped out of the cell and potassium ions are pumped into the cell. This results in a more negative charge inside the cell, which can inhibit the cell's ability to respond to stimuli.
Hyperpolarization is the opposite of depolarization, which is a process that leads to a decrease in the negative charge within a cell and an increase in the cell's excitability. Hyperpolarization can be triggered by various stimuli and plays a role in the normal functioning of the nervous system.

6. What is the relationship between genes and alleles?
Answer:
A gene is a unit of hereditary information. Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits. Alleles are also genetic sequences, and they too code for the transmission of traits. So, what it is the difference between a gene and an allele? The short answer is that an allele is a variant form of a gene.

Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1. Algae have a variety of adaptations that help them survive including body structures, defense mechanisms, as well as reproductive strategies. Some algae have holdfasts that attach to the sea floor and anchor them down much like roots of a plant. Many algae, such as Sargassum, have gas-filled structures called floats.
2. Algae and plants are like humans as they need food, nutrients and a good environ- ment to grow and survive. Algae make their own energy or food from the sun but they also need water, correct temperature and nutrients to grow. Algae live in water or damp environments
3. In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration

When describing a group of animals, you speak about an ancestral species and some but not all of its descendants. This is an example of a _____. Group of answer choices monophyletic group polyphyletic group paraphyletic group
Answer:
This is an example of a paraphyletic group.
Explanation:
Paraphyletic groups is a group that contains only part of the descendants of a common ancestor. A group is constituted as paraphyletic when one or more holophyletic groups are subtracted from a clade (evolutionary branch). Traditional classifications are loaded with paraphyletic groups, such as invertebrates, pteridophytes, opposites. In each of these cases the group is defined by the exclusion of a smaller group within a larger one. An example is the reptiles are a paraphyletic group, since when we refer to them we are excluding mammals and birds even though they are taxa that evolutionarily descend from reptiles.

A Scientist discovers a chemical that she thinks might be a potential treatment for a certain type of cancer cell. In order to test her hypothesis, the scientist treats one plate of cancerous cells with the newly discovered chemical, and leaves another plate of cancerous cells untreated. After 7 days, the scientist measures the number of living cells in each plate. The scientist finds that the cells treated with the chemical have a lower survival rate than cells left untreated. The scientist further observes that the substance has an effect on the Rough endoplasmic reticulum (RER). How might disabling the rough ER potentially hurt the cancerous cells? Be specific in your answer. What is the dependent variable? What is the independent variable?
Answer:
Affecting the ER causes alteration in cell homeostasis and eventual death.Independent variable: Drug or chemicalDependent variable: Cancer cells survival.Explanation:
Hypothesis ⇒ A chemical ⇒ might be a potential treatment for cancer cells.
Experiment:
Treated ⇒ One plate of cancerous cells with the new chemicalUntreated ⇒ Another plate of cancerous cells with no chemical7 days later ⇒ the number of cells in each plate
Results:
Cells treated with the chemical have a lower survival rate than cells left untreated.
Treated plate ⇒ fewer cellsUntreated plate ⇒ more cellsChemical affects the Rough endoplasmic reticulum (RER)
----------------------------------------------------------------------------------------------------------
The endoplasmic reticulum is in charge of many cellular functions, such as protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction.
When the synthesizing protein gets in the Rough endoplasmic reticulum, it continues its building in the organelle. Finally, the protein suffers folding and the initial stages of glycosylation.
Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex for their final association with carbohydrates. Finally, protein leaves the Golgi complex and goes to its final destiny.
Any alteration in the intracellular environment
inevitably affects the organelle and its functions. When the organelle is not properly working, proteins synthesis is affected and, consequently, all the cellular activities. The affected cell homeostasis might be so altered that the cell ends dying.
If the drug affects the ER by altering its environment or directly affecting it, the organelle will fail to perform its functions, and the cell will eventually dye.
------------------------------------------------------------------------------------------------------------
The independent and the dependent variables are the two principal factors needed in an experiment.
Independent variable: Refers to all the variables in an experiment that provoke a response in another variable. The independent variable changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter.
In the exposed example, the independent variable is the drug that affects the cancer cells. The researcher decides to apply it or not, and the concentrations in which the drug is.
Dependent variable: Refers to the variable that reacts to the changes produced in the independent variable. Depending on how the independent variable is modified, the dependent variable change. It is usually identified by the letter Y.
In the exposed example cell survival is the dependent variable. Cancer cells respond to the presence/absence of the chemical, and might differently respond to the varying concentration of the drug.
The BRCA-1 genes in humans encode proteins that have role in maintaining DNA stability. Mutation in this gene results in formation of non-functional protein, which is not able to repair damaged DNA, resulting in a significantly increased risk of breast cancer. BRCA-1 is a/an: Group of answer choices Proto-oncogene Homeotic gene Oncogene Tumor suppressor gene
Answer:
tumor suppressor gene
Explanation:
A tumor suppressor gene is capable of modulating cellular processes during cell division and/or replication, thereby avoiding uncontrolled cell proliferation and tumor development. For example, the p53 gene is a tumor suppressor gene that encodes a protein (p53) which is well known to regulate critical cellular processes such as, for example, cell cycle arrest and programmed cell death (apoptosis). Moreover, breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes that regulate the repair of damaged DNA through the Homologous recombination (HR) pathway. In consequence, mutations in BRCA1 and BRCA2 genes can increase the risk of developing breast cancer.

How is The processes of photosynthesis and respiration are interrelated
[tex]\color{Black}\huge{Answer} [/tex]
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.Answer:
Carbon dioxide and water are converted to oxygen and glucose through photosynthesis.
Oxygen and glucose are converted into water and carbon dioxide through cellular respiration.
By-products include water and carbon dioxide, while ATP is the energy generated by the process.
Explanation:
Plants use light water and carbon dioxide to make energy (glucose) and oxygen through photosynthesis. The oxygen is released into the atmosphere while the glucose powers the plant's operations. The process through which animals mix glucose and oxygen to make carbon dioxide and water is known as cellular respiration.
Photosynthesis end product is glucose utilised for the production of ATP in the cellular breathing. Glucose is then returned to carbon dioxide, needed for photosynthesis. During photosynthesis, the water is broken down into oxygen, but oxygen is mixed with hydrogen into water in cell respiration.

What are wetlands?Wetlands are defined as areas where water either completely covers the soil or is present either at or near the surface of the soil throughout the entire year or for varying amounts of time at different times throughout the year, including during the growing season.
Our water is cleaned by wetlands because they filter out sediments, other pollutants, and even chemical contaminants. Additionally, wetland areas act as a filter for and a processing facility for excess nutrients that may run off from agricultural and development sites. Historically, people have referred to wetlands as "the kidneys of our watershed."
