How did scientists prove that the food is transported through the phloem
Answer:
When a aphid is killing at the act of feeding then the body is carefull cut away but the proscis still inserted into the phloem then the food slowly exuded form cut end of the proboscis in the form of drops. These drops contain sugar and amino acids which means food is transported through phloem in plant.
NEED THIS ASAP Which of the following is (are) part of a systemic immune response?
I. A fever
II. An increase in white blood cells in the body
III. An inflammatory response
I only
II only
III only
I and II only
I, II, and III
Answer:
I, II, and III.
Explanation:
Immune response may be defined as the type of response generated by the body against the pathogens. The immune response is important to kill the pathogens.
Fever is a type of immune response generated to kill the pathogen by increasing the body temperature. The number of white blood cells of the body increases to fight against the pathogen. The inflammatory response may also generated to kill the pathogen.
Thus, the correct answer is option (E).
One gene in the human genome may be expressed at a much higher level than another. Can differences in types of cis elements present account for this
Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
Cis-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene transcription. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate gene expression levels.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.

Which are examples of active transport?
Select all that apply.
exocytosis
phagocytosis
diffusion
pinocytosis
Answer:
Exocytosis, phagocytosis, and pinocytosis
Explanation:
Active transport is when energy is used to move substances across the cellular membrane.
Exocytosis requires energy to remove materials from the cell; it is active.
Phagocytosis also requires energy; it is active.
Diffusion isn't active because it moves materials down their concentration gradient and therefore it doesn't require energy.
Pinocytosis is a form of endocytosis and requires energy; it is active.

define osmoregulation
Answer: OK!
Explanation: Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

What is the potential energy of a 10-kg book that is placed on a shelf that is 2.5 meters high?
The potential energy of the book is 245 J.
SOLUTION:We are given the following:
mass m = 10 kgheight above a reference point h = 2.5 mUse the formula for potential energy. ( g = 9.8 m/s² )
[tex] \qquad {\boxed{\sf P.E._{grav} = m \times g \times h}} [/tex]
[tex] \sf P.E._{grav} = (10\:kg) \times (9.8\: \frac{m}{s^2}) \times (2.5\:m) [/tex][tex] \sf P.E._{grav} = (10\:kg) \times (24.5\: \frac{m^2}{s^2}) [/tex][tex] \sf P.E._{grav} = {\boxed{\sf {245\:J}}} [/tex]Therefore, the potential energy of the book is 245 J.
HOPE IT HELPS!Describe a freshwater biome.
Define a wetland.
Why do wetlands have high biodiversity?
A developer wants to extend a golf course into a wetland. Outline environmental arguments you could make against this plan.
Freshwater biomes are large communities of plants and animals centered around waters with less than 1% salt concentration. They are very important to survival on Earth. Types of freshwater biomes include ponds, lakes, streams, rivers, and even some wetlands. Wetlands are not always considered freshwater biomes because they usually have too high of a salt content.
2.
Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year.
3.
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.

Which of the following is NOT an accessory gland of the male reproductive system?
Answer:
a. Testosterone gland
Explanation:post protected
Testosterone gland is not an accessory gland of the male reproductive system.
What is Testosterone gland?Testosterone is a hormone that is primarily produced in the testicles in males and in small amounts in the ovaries and adrenal glands in females. It is a vital hormone that plays a critical role in the development of male reproductive tissues and secondary sexual characteristics, such as muscle mass, bone density, and body hair growth.
Testosterone is also essential for maintaining sex drive and overall physical health in both men and women. The production of testosterone is regulated by the hypothalamus and pituitary gland in the brain, which release signals to the testes to produce testosterone.
Certain medical conditions, lifestyle factors, and aging can affect testosterone production and levels, which can have significant impacts on health and wellbeing. Treatment options are available to address testosterone deficiencies and imbalances.

Does the waxy cutie affect where acertain pla y could be grown? Why?
Waxy skin - some leaves have a thick, waxy skin on their surface. This reduces water loss by transpiration . Water storage - some plants, known as succulents, store water in their stems, leaves, roots or even fruits.
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". ... The purpose of this covering is to help the plant retain water. In arid regions, that is very important. In wetter regions, the waxy coating may help prevent infection by disease organisms.
Plants that grow in arid zones of USDA zones 9 to 11 use waxy leaves to limit transpiration and retain water but also to protect leaves from the frigid temperatures sometimes found in the desert. Trees like the desert willow (Chilopsis linearis) have narrow, waxy leaves and striking purple flowers.

explain how a molecule of carbon dioxide from the atmosphere teaches the site of photosynthesis in a leaf
Answer: On the surface of the leaves of the plants there are a large number of tiny pores known as stomata or stoma. For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells.
Explanation:
In sexual reproduction, will an offspring show a recessive trait if just one of its parents has recessive alleles for that trait? Explain your answer.
Answer:
No, they will not
Explanation:
In this question, we assume that the parents have genotypes of rr and RR (I use "r" out of convenience). If we cross both of these parents, it is impossible for any of the offspring to be rr like the one parent. They would all be heterozygous. If the other parent had a single recessive allele, then it would be possible.
