Answer:
Both transfer thermal energy from warm objects to cooler objects.
Explanation:
Radiation involves the transfer of energy in the form of light, heat and electromagnetic waves such as x-rays while conduction involves the transfer of energy through direct contact of the two substances. The both of them involve involve the transfer of thermal energy from hotter objects to colder objects.
Radiation is involved in the transfer of energy through empty spaces while conduction involves transfer of energy through direct contact.
The statement which best compares radiation and conduction is both transfer thermal energy from warm objects to cooler objects.
To answer the question, we need to know what heat transfer is
What is heat transfer?This is the transfer of thermal energy from one body to the other.
Types of heat transferThere are 3 types of heat transfer namely
Conduction - This is the transfer of thermal energy from warms objects to cooler objects through direct contact. This usually occurs in solids.
Convection - This is transfer of thermal energy from warmer objects to cooler objects by movement of the whole object. This usually occurs in fluids.
Radiation - This is transfer of thermal energy from warm objects to cools objects through empty space by electromagnetic waves.
So, the similarity between conduction and radiation is that both transfer thermal energy from warm objects to cooler objects.
So, the statement which best compares radiation and conduction is both transfer thermal energy from warm objects to cooler objects.

Elodea is a plant that lives in water. Like all plants, elodea can make its own food through
process called photosynthesis. Oxygen gas is also produced during photosynthesis.
Photosynthesis can only happen in the presence of light. To measure the rate of
photosynthesis, a piece of elodea can be placed in an inverted test tube filled with a
sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the
top of the test tube.
A student has designed an experiment using elodea plants. The experimental setup is
shown in Figure 1-4
Which of the setups would serve as the control of the experiment?
Bucket
Lamp
Flashlight High
Natural
Elodea
Sodium
bicarbonate
solution
The controlled variable is kept constant during the whole experiment in all the different study groups. In this experiment, Sodium bicarbonate solution is the controlled variable.
------------------------
During an experiment, the controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In this experiment,
The independent variable → presence/absence of light reaching the plant. The researcher regulates the amount of light by using different elements such as the bucket, lamp, flashlight, and natural light. The dependent variable → oxygen production through which the researcher measures the photosynthesis rate. The controlled variable → Sodium bicarbonate solution. It provides carbon dioxyde, and must be constant in the four scenarios to avoid an effect on the results.-----------------------

Two groups of tomatoes were grown in the laboratory, one with humus added to the soil and the other a control without humus. The leaves of the plants grown without humus were yellowish (less green) compared with those of the plants grown in humus-enriched soil. The best explanation for this difference is that __________.
Answer:
The best explanation for this difference is that the humus contained micronutrients needed by the plants for the synthesis of chlorophyll, such as Manganese (Mn), Iron (Fe) and Copper (Cu).
Explanation:
Chlorosis is the yellowing of plant leaves, and this is due to the deficiency in the amount of chlorophyll contained in the plant leaves. Iron (Fe) is an essential micronutrient for the synthesis of chlorophyll, which is an enzyme-catalyzed reaction. Copper (Cu) is a component of most enzymes, while Manganese (Mn) is a cofactor, required for the activation of the enzymes that catalyze chlorophyll synthesis, hence deficiency of these nutrients will result in the development of chlorosis.

A population of birds can have large, heavy beaks or thin, long beaks.
What can we say based on this data?
Select one:
We cannot conclude anything without having more data.
Having heavier beaks is a survival advantage.
Having longer beaks is a slight survival advantage, but having more data would help to confirm.
undo
There is no survival advantage between having heavier beaks and longer beaks.
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
TLRs are Group of answer choices the coatings of pathogens by complement. present in intact skin, sebum, tears, etc. phagocyte receptors that detect PAMPs. nonspecific leukocytes that secrete toxins onto the surface of virally infected cells. molecules that damage cells, resulting in cell lysis.
Answer: Phagocyte receptors that detect PAMPs
Explanation:
TLRs or Toll-like receptors, are a family of proteins that are part of the innate immune system. TLRs are transmembranous and recognize pathogen-associated molecular patterns (PAMPs), which are groups of chemical characteristics common to certain types of pathogens. Patterns detected by TLRs include lipopolysaccharide, a compound found on the surfaces of Gram-negative bacteria, and double-stranded RNA, which is an integral part of the life cycles of many viruses. These PAMPs are generally important for the survival of the pathogen, so they are well preserved. Activation of these receptors induces inflammatory responses in leukocytes of myeloid lineage, signaling via NF-κB, which is a transcription factor that activates pro-inflammatory genes. Activated TLRs also increase the production of co-stimulatory molecules such as CD80, CD86 and CD40. These proteins, expressed on the surface of antigen-presenting cells, are necessary for the activation of T-lymphocytes by dentritic cells and macrophages already showing antigens in their MHC type II molecules (Major Histocompatibility Complex, they participate in the presentation of antigens to T lymphocytes)
In addition, TLR-mediated signaling on antigen-presenting cells (APCs) plays an important role in linking the innate and adaptive immune responses.

Food moved to the back of the mouth by the tongue causes all of the following EXCEPT covering the opening of the larynx by the epiglottis. pressure against the pharynx to initiate swallowing. elevation of the soft palate to seal off the nasal cavity. the swallowing center stimulates successive waves of muscle contraction in the esophagus. churning of the stomach contents.
Answer:
churning of the stomach contents.
Explanation:
When food is moved to the back of the mouth by the tongue (deglutition), it does not cause the churning of the stomach contents.
The churning of stomach contents occurs when the bolus from the mouth has entered through the lower esophageal sphincter into the stomach. Churning is the mixing of the bolus with digestive juices containing acids and enzymes secreted from the stomach lining.
What are intermediate species? in an easy way to understand. And some examples?
Answer:
An intermediate is a species which appears in the mechanism of a reaction, but not in the overall balanced equation. Examples: Amphibian/land vertebrate (Pederpes)- Intermediate form between primary aquatic Upper Devonian amphibians and early tetrapods. Lizard/snake (Pachyrhachis)—Intermediate form of snakes and an extinct lizard-like reptile. It was a primitive snake with limbs.
Explanation:
Answer: These are certain species that create “connecting links” or something like that, between the fossil record of life which help to show the slow process of speciatin.
