The negative effects of chemical control of weeds on rangelands
Answer:
Chemical residue remain on the vegetation.
Explanation:
The negative effects of chemical control of weeds on rangelands is that the chemical residue remain on the vegetation in rangeland which is dangerous for animals that feed on vegetation because the chemicals are toxic that cause serious damaged. Sometime the chemical also damaged the weeds as well as vegetation of rangelands and also kill the beneficial insects that is needed by the plants present in rangelands.

Would an observational study or an experiment be more appropriate to investigate the effects on fertilizer on plant growth? Explain.
Answer:
Experiment
Explanation:
For such an investigation an Experiment would be the better option. This is because in an experiment you would have both an experimental group and a control group. This would allow you to use fertilizer on one but not the other, therefore, providing seperate results that you can use to compare with one another. This ultimately helps you determine the actual effects that fertilizer has on the growth of plants, since the fertilizer would be the only variable in the experiment. An observational study would only allow you to observe the plants in a natural scenario, without interfering and seperating the plants into different groups with different environments.

Which type of medications are manufactured as an antigen against the disease-
causing bacteria or virus and then administered to healthy individuals to produce
adaptive immune response?
Chemotherapy drugs
Immune-modulators
Vaccines
Alkylating agents
Please help. Thx
Answer:
Vaccine are manufactured as an antigen against the disease-causing bacteria or virus and then administered to healthy individuals to produce adaptive immune response
The type of medications are manufactured as an antigen against the disease- causing bacteria or virus and then administered to healthy individuals to produce adaptive immune response is Vaccines which is the third option.
Vaccines are medications that are manufactured as an antigen against disease-causing bacteria or viruses. They are designed to stimulate the immune system of healthy individuals to produce an adaptive immune response. By introducing a harmless or weakened form of the pathogen or its components into the body, vaccines mimic an infection and trigger an immune response. This allows the immune system to recognize and remember the pathogen, enabling a faster and more effective response if the person is exposed to the actual disease-causing agent in the future.

You isolate a variant of the Hfr parent in question 6 that only shows recombination of the his+ and trp+ genes. The cross was ( HFR lac+, gal+, trp+, his+, strr X F- lac-, gal-, trp-, his-, strs ). This strain most likely:_________.
a. Contains an F' his+ trp
b. Has become F-
c. Contains an Hfr translocation
d. No longer mates as a merry diploid
e. Not enough information is given
Answer:
The correct answer is - b. has become F-.
Explanation:
In the case of the cross of two different strains, some genetic material moves to the F- strain from the Hfr strain, but due to genome size, it's not possible that all the genes can pass into a single bacterium.
Instead of complete transfer, each individual F- cell gets a different and random subset of genes from the Hfr. There is no translocation and F' does not contain his+ trp+.
Methylene blue can be used to stain DNA because it: (2 pts) forms ionic bonds with DNA changes the pH and therefore the structure of DNA makes DNA electron dense is an effective chemical fixative for cells is none of the above
Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).
Explanation:
To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.
The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.
Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).
When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.
Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.

¿Qué importancia tiene el agua en las reacciones químicas?
Answer:
El agua es un medio ideal para reacciones químicas, ya que puede almacenar una gran cantidad de calor, es eléctricamente neutral y tiene un pH de 7.0, lo que significa es que no es ácida ni básica. Además, el agua participa en muchas reacciones enzimáticas como agente para romper enlaces o, al eliminar de una molécula, para formar enlaces.
Explanation:
Note that arteries have a thicker middle layer of tissue than veins. Why is this important and how does it affect the structure of the artery as compared to the vein?
Answer:
The correct answer is - To withstand the high pressure of the outflow of blood from the Heart.
Explanation:
The heart pumps blood to different body parts at high pressure so that it can easily reach all the parts of the body quickly. To able to hold the pressure of the blood pumped at high-pressure arteries need thick walls.
This pressure can be experienced as pulse and which required the walls of arteries and the middle layer or the tunica media to make it much thicker in arteries than in veins. In veins pressure caused by blood is very low pressure that allows them to be thin walls.

Explain how the ear helps humans in balancing.
Answer:
The vestibular system which is essential to our sense of balance is located within the inner ear
Explanation:
The vestibular system is the sensory apparatus of the inner ear that provides the brain with the information required for maintaining body balance (postural equilibrium), detecting the position and motion of the head and determining the position of the whole body in relation to gravity. The vestibular system in each inner ear is composed of five organs: 3 semicircular ducts located in the innermost part of each ear (i.e., the inner ear), which are sensitive to angular accelerations (head rotations), and 2 otoliths organs referred to as the utricle and saccule, which are sensitive to linear accelerations. Each semi-circular duct exhibit a different orientation (superior, horizontal, and posterior) in order to sense different movements (e.g. nodding, rotating).

Our understanding of many of the evolutionary relationships among animals changed after those phylogenies were based on morphological and molecular data (as opposed to only using morphological data). Which of the following groups represents an example of this change?
a. Lochotrophozora
b. Bivalvia
c. Brachiopoda
d. Placozoa
Answer:
a. Lochotrophozora
Explanation:
Molecular research and studies complement morphological research and improve our awareness and knowledge of evolutionary history. Previously, morphological studies could only reveal to us the variations and distinctions, but molecular studies and phylogeny have enabled us to pinpoint the fundamental mechanism of this variation on a genetic level, as well as locate it down to evolutionary lineage, which has led to more enhanced genealogy and evolutionary studies.
However, the group of organisms that best reflects and represents this kind of change is: Lochotrophozora
Groups represent an example of this change is option "A" which is Lochotrophozora.
What is Lochotrophozora diversification?Lophotrochozoa is a monophyletic group of animals that includes annelids, molluscs, bryozoans, brachiopods, Platyhelminthes, and other animals that descended from the common progenitor of these organisms.
Lophotrochozoa is one of the three major clades that include bilateral animals, or Bilateria.
Thus, option "A" is Lochotrophozora.

Why do you think so many people seem to not care about the environmental issues we are facing?
Answer:
People are not aware of their causes and impacts.
Explanation:
First, people just seem to think that a little bit of harm won't impact the world at all, but that little bit for everyone adds up and the magnitude is a lot worse than people would imagine. Next, even if they/we do know the scale, they don't know how to help or are not interested enough to try and fix the problem. We all think that we won't be able to help enough to fix the issue.
