Pesticides often do not just kill the target pest but also poison
inects in and
around the fields. These insects with the pesticides can be eaten by other animals and poison them.
Some pesticides are suspected of disrupting the
of wildlife and people. These
chemicals
because they are fat soluble and get passed up the food chain
by
Unlike pesticides, fertilizers are not directly toxic but their presence in
freshwater and marine areas alters the
system, and in consequence the species
composition of specific ecosystems. Their most dramatic effect is
resulting in an
explosive growth of algae due to
nutrients. This depletes the water of dissolved
oxygen, which in turn can kill fish and other aquatic life.
Answer:
Other problems of pesticide use include most pesticides kill beneficial species as well as the target pest species, pesticides do not stay put, pesticides harm wildlife, and pesticides can threaten human health. Farmers pay more and more for a pest control program that often becomes less and less effective.

This pedigree chart tracks the inheritance of a recessive trait that is not sex-linked. Based on the information in the chart, which of the following statements is true about individuals 3 and 4?
At least one is hete rozygous for the trait.
They are both hom ozygous dominant for the trait.
They are both hete rozygous for the trait.
At least one is hom ozygous for the trait.
Answer:
C. They are both heterozygous for the trait.
Explanation:
It is not possible for both parents to be hom ozygous dominant, as that would only produce hom ozygous dominant children, and from the chart they have one child that is recessive.
It is not possible for only one parent to be heter ozygous, as again, that would only produce dominant children.
Lastly, it is not possible for only one to be hom ozygous, because that again would only result in dominant children.
Pairing two heter ozygous parents would result in a 25% chance of a recessive child.

Can someone do this quick?
Answer: A.
Explanation:
Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.
Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.
The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.
Streptococcus mutans is one of the bacteria responsible for dental plaque formation and lacks an outer membrane outside its cell. Structurally and morphologically how would S. mutans look under the microscope. Illustrate the appearance
Answer:
The illustration is attached.
Explanation:
Under a microscope, Streptococcus mutans would be seen as small oval structures, about 0.5 to 0.75 µm in diameter. These structures would be linked to putras in pairs, or in a type of horizontal chain.
To survive, this bacteria must be present in places rich in organic matter and nutrients.

. Two students are discussing natural selection in bacteria and how it can relate to antibiotic resistance in
bacteria.
Bernadette states that when antibiotics are used, bacteria can respond by developing traits to help them
defeat the antibiotic, which then may increase their fitness.
Dominique states that there is already a variety of traits among the bacteria. Bacteria that have traits that
allow them to survive the antibiotic and reproduce may have higher fitness.

how is the hydrosphere connected to the lithosphere
Answer:
Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (lithosphere), or evaporating into the air (atmosphere). Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (lithosphere) to produce electricity.

At what point is a star born?
Answer:
when it's born a star is born when it's born
Answer:
A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin

Which of the following statements is true?
O During fission, hydrogen is split apart into helium.
O U-235 is created from nuclear fusion reactions.
Exothermic reactions absorb heat and light.
The sun uses some of its own mass during fusion reactions.
C
Me To
Answer:
The sun uses some of its own mass during fusion reactions.
Explanation:
This is because the sun consist of hydrogen and helium. And the sun gravity compresses the gases hydrogen and helium and they become hot.
Heat and pressure forces hydrogen together to form helium which is nuvlear fusion.
Nuclear fusion is the combination to two nuclei or more nuclei to form one or more subatomic nuclear.

Complete question:
You will find the complete question in the attached files
Answer:
1)
Alienus quadlegicus: Mouth opened and no armsAlienus hairicus: Mouth opened, hairyAlienus tritoothicus: Mouth opened, not hairyAlienus stripicus: Mouth not opened, hornsAlienus bloblicus: Mouth not opened, No legsAlienus fuzzicus: Mouth not opened, Legs2) Genus Alienus
3) Morphological characteristics of aliens are used to identify them and to name them.
Explanation:
1) The dichotomous keys give you information about the groups that are being differentiated to correctly identify them. All you need to do is follow the description of the organisms and the numbers where each description drives you. If you observed correctly the organism, you will reach the scientific name, or genus, or any other taxonomic group you are looking for.
2) Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships. A binomial name is assigned to each organism, composed of a genus and the epithet.
Among all the categories where organisms are classified, we can find the genus, which includes many species that share some common characteristics that are used to group them together.
In this example, Alienus is the genus of all these aliens species.
3) Morphological characteristics of aliens are used to identify them and to name them.
Alienus quadlegicus: Four-legged alienAlienus hairicus: Hairy alien.Alienus tritoothicus: Alien with three teethAlienus stripicus: Alien with striped hornsAlienus bloblicus: Alien with no shape. Shapeless massAlienus fuzzicus: Short fine-haired alien.

According to the National Institute of Health, atrial fibrillation (A-F) occurs if rapid, disorganized electrical signals causing the heart's two upper chambers, called the atria, to fibrillate. The term "fibrillate" means to contract very fast and irregularly. In A-F, blood pools in the atria. It isn't pumped completely into the heart's two lower chambers, called the ventricles. As a result, the heart's upper and lower chambers don't work together as they should. Based on the passage above, how will atrial fibrillation affect blood pressure?
A. It will lower blood pressure because less blood is pumped per beat.
B. It will increase blood pressure because the heart is contracting faster.
C. It will increase blood pressure because the atria fill fully with blood.
D. It will lower blood pressure because blood volume drops in the atria.
Answer:
A. It will lower blood pressure because less blood is pumped per beat.
Explanation:
I thought B might be a potential answer, but since the atria are not filling properly and heart rate is increased, it would make sense that blood pressure drops (effect of faster heart contraction is negated by the drop in blood volume in the atria).

The six modes of disease transmission shown in the Model 2 are
1. Airborne
What is airborne?The Airborne transmission can be caused by coughing, sneezing where
water droplets carry the disease causing organisms.
Example: flu, tuberculosis, etc.,
2. Food borne or waterborne
The pathogen is transmitted by the consumption of contaminated
food or water
Eg: cholera, botunilsm, etc.,
3. Vector
The vector such as insects or animals can act as vectors by carrying disease causing malaria, dengue.
4. Blood borne
The disease is caused by the transmission of blood or contact of
injured cuts or incisions.
Example: hepatitis, AIDS, etc
5. Contact
The disease is caused by the person to person direct contact of skin to skin such as leprosy, skin and eye infections, fungal infections, etc.,

What are the differences between flatworms and sponges
Hello Beautiful People!
I was wondering if anyone had made a study guide for the Cambell Biology textbook
What process occurs at the boundary between the capillaries and the alveoli?
A.
Nitrogen enters the alveoli, and oxygen enters the capillaries.
B.
Oxygen enters the alveoli, and carbon dioxide enters the capillaries.
C.
Oxygen enters the alveoli, and nitrogen enters the capillaries.
D.
Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Answer: D. Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Explanation:
This describes the exchange of gases in the lungs. When blood from the rest of the body gets to the lungs through the capillaries, oxygen flows from the alveoli which are tiny air sacs in the lungs, into the blood in the capillaries.
Carbon dioxide from the blood brought to the lungs will then flow into the alveoli which will then expel it through the nose. This repeated process ensures that the body keeps getting oxygen and expelling carbon dioxide.
