Answer:
B. Air density decreases at higher altitudes
Explanation:
Since air is compressible, air from higher altitudes will compress air from lower altitudes. As a result, air density at lower altitudes will be greater than air density at higher altitudes. Air particles at the highest altitudes, not being acted upon by air above it, will be more spread out.
Which product is the result of light reactions in photosynthesis?
A. Water
O B. Glucose
O C. Oxygen
O D. Carbon dioxide
Answer: C) Oxygen
Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.

Which solution is more concentrated?
Solution 1:
500 mL of water
100 g of salt
Solution 2:
500 mL of water
90 g of salt
A. Solution 1
B. Solution 2
C. Both have the same concentration
Answer:
A (Solution 1)
Explanation:
Since both solutions have an equal volume but Solution 1 has a greater amount of solute (100 g in Sol. 1 > 90 g in Sol. 2), Solution 1 is more concentrated.
Lions and Tigers are the most similar of the "Big Cats". Why are Lions and Tigers so similar?
Big Cats | Big cats art, Wild cats, Big cats
Question 4 options:
because lions and tigers both need to hunt
because lions and tigers have many of the same genes
because lions and tigers have the same type of cells
because lions and tigers share the same organelles
Answer:
B. Because lions and tigers have many of the same genes.
Explanation:
You can rule out A, since all big cats and other predatory animals must hunt to survive.
C can be ruled out, as all animals have roughly the same cells.
D can be ruled out as well, since all animal cells have the same organelles (essentially the same reason C can be ruled out.)
That leaves us with option B. B is the most likely answer, as lions and tigers share most of their DNA with one another.
write a short note on gender issues and mites associated with female infanticide
Answer:
gender issues include all aspects and concerns related to women's and men's lives and situation in society, to the way they interrelate, their differences in access to and use of resources, their activities, and how they react to changes, interventions and policies.
female infanticide is the deliberate killing of newborn female children. In countries with a history of female infanticide, the modern practice of sex-selective abortion is often discussed as a closely related issue. Female infanticide is a major cause of concern in several nations such as China, India and Pakistan. It has been argued that the low status in which women are viewed in patriarchal societies creates a bias against females.
In 1978, anthropologist Laila Williamson, in a summary of data she had collated on how widespread infanticide was, found that infanticide had occurred on every continent and was carried out by groups ranging from hunter gatherers to highly developed societies, and that, rather than this practice being an exception, it has been commonplace. The practice has been well documented among the indigenous peoples of Australia, Northern Alaska and South Asia, and Barbara Miller argues the practice to be "almost universal," even in the West. Miller contends that female infanticide is commonplace in regions where women are not employed in agriculture and regions in which dowries are the norm. In 1871 in The Descent of Man, and Selection in Relation to Sex, Charles Darwin wrote that the practice was commonplace among the aboriginal tribes of Australia.
In 1990, Amartya Sen writing in the New York Review of Books estimated that there were 100 million fewer women in Asia than would be expected, and that this amount of "missing" women "tell[s] us, quietly, a terrible story of inequality and neglect leading to the excess mortality of women." Initially Sen's suggestion of gender bias was contested and it was suggested that hepatitis B was the cause of the alteration in the natural sex ratio. However it is now widely accepted that the numerical worldwide deficit in women is due to gender specific abortions, infanticide and neglect.
In seventh-century Arabia, before Islamic culture became established, female infanticide was widely practiced. This is attributed by scholars to the fact that women were deemed "property" within those societies. Others have speculated that to prevent their daughters from a life of misery, the mothers would kill the child. With the arrival of Islamic rule the practice was made illegal.
how Is the energy for an earthquake generated?
According to the USDA, a "consists of a community of individuals who pledge support to a farm operation so that the farmland becomes,
either legally or spiritually, the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits
of food production."
-sustainable operation
-farmers' market
-farmers' cooperative
-CSA
Answer:
The correct answer is CSA.
Explanation:
Community Supported Agriculture (CSA) is an alternative model for the distribution of agricultural products directly from the farmer to the consumer, it consists of a group of people who form a cooperative to grow and consume food. Through this socio-economic model, consumers lend their support to producers, in exchange for a direct and regular delivery of biological products, that is, producers and consumers support each other and share the benefits and risks of food production.

What is added as an anticoagulant to preserve blood specimens?
OA sodium citrate
B
sodium fluoride
O'c. potassium oxalate
OD liquid paraffin
E.
ethanol
Reset
Answer:
C. potassium oxalate for plato / edmentum
Explanation:
I took notes in the class and my notes say -
To prevent blood from clotting, toxicologists add anticoagulants to the blood sample. Anticoagulants such as potassium oxalate (30 mg/mL) is preferred over heparin or ethylenediaminetetraacetic acid (EDTA) because both heparin and EDTA interfere with the detection of certain chemicals, such as calcium, in the blood. If the blood is suspected of carbon monoxide poisoning, a layer of liquid paraffin is added over the blood sample. This layer prevents exposure to atmospheric oxygen.
Results from multiple experiments suggest that the ActA protein of Listeria, an integral membrane protein expressed on the cell surface, is the only bacterial protein that is required for the movement of the bacterium within its host cell. Which combination of the following observations shows that ActA is both, necessary and sufficient for bacterial movement?
I. ActA binds to the Arp2/3 complex
II. E. Coli in which ActA is expressed moves in host cell cytosol
III. Listeria lacking the ActA gene fail to move inside the host cell cytosol.
IV. ActA has 3 transmembrane domains
V. Arp2/3, when activated, nucleates a branched actin network
a. I and II
b. II and III
c. I and III
d. III and IV
e. I and V
Answer:
b. II and III
Explanation:
The Actin assembly-inducing (ActA) protein is an integral membrane protein localized on the bacterial surface. It has been shown that ActA is necessary and sufficient to induce bacterial movement within host cells, regardless of other proteins. The function of the ActA protein for bacterial movement within host cells was discovered by identifying mutant Listeria bacteria for the gene encoding this protein which were unable to spread from cell to cell. Subsequently, by inducing mutations in other genes of the bacterial genome, researchers discovered that actA was the only protein involved in the actin assembly, which is required for cell-to-cell spread.

Within a plant, photosynthesis is critical. It provides cells with the glucose they need for
energy. Photosynthesis is important for another reason, too. It's part of the flow of carbon
through organisms and the environment. This cycle, known as the carbon cycle, is essential
for life on Earth. It includes several processes that are occurring all the time. When plants
photosynthesize, carbon is removed from the atmosphere as carbon dioxide. When animals
and plants use cellular respiration, carbon is released into the atmosphere as carbon
dioxide. Organisms that die and are buried for millions of years turn into fossil fuels, which
are made of carbon. When humans burn those fossil fuels, carbon is released into the
atmosphere as carbon dioxide. Without enough carbon dioxide in the atmosphere, the
planet would be too cold. But too much carbon dioxide contributes to the warming of the
planet that could make it too hot to survive.
Based on the passage, what is one reason that the carbon cycle important?
A It adds carbon into the atmosphere whenever the level begins to drop too low.
B
It helps maintain a level of carbon in the atmosphere that is neither too hot nor
too cold.
с
It removes carbon from the atmosphere whenever the level begins to become
too high.
D
It releases carbon into space, preventing it from building up in Earth's
atmosphere.

A group of lions is chasing a zebra. The lions are most likely responding to which kind of stimulus?
the external stimulus of fear
the internal stimulus of fear
the external stimulus of hunger
the internal stimulus of hunger
Answer:
internal stimulus of hunger
Explanation:
Lions do not fear externally or internally of the zebra because they eat the zebra once they kill it and they are chasing after it so no fear what so ever.
Lions are naturally lazy and hunger is normally why they would be hunting because they need food to survive, however this is not always the case.
there have been a pair of documented pair of male lions known as the Tsavo Man-Eaters, who hunted for sport. Their den contained animal and man bones.
they actually made a movie about it, If you want to watch the movie just look up Ghost in the Darkness. You can actually see the lions in the Field Museum of Natural History in Chicago, Illinois.

There was a rise for nationalism( a negative thing mind you, that discriminates against "non-Americans") in the early 20s, and it affected most of Americas judgement of a fair trail (and treatment in general) towards immigrants.
Determine the parental genotypes and proportion of offspring genotypes for locus 2. What are the genotypes of the parents with respect to locus 2 (i.e., alleles B and b)
Answer and Explanation:
Alleles are the different varieties of genes. For every gene, somatic cells have two alleles.An allele that is not expressed by an organism might be passed to the offspring of The organism provides one allele.
It is difficult to conclude which two alleles of a gene exist within the chromosomes of organisms. that organism and can express in the next generation.
The parental genotypes can be determined by PUNNETT SQUARE, in which we use two letters to signify the genotype.
As the white throat code and the red throat code are alleles.
A lowercase letter represents the recessive form of a gene (allele), and a capital letter represents the dominant form of a gene (allele). For example, for the red-throated bird, white throat is a recessive trait, and red throat is a dominant trait.
There are basic steps of using Punnett Square. Step one is to determine the parent organism genotypes then write down “mating.” Draw a p- square. For each parent, split the letters of the genotype. Then place them outside the p-square. By filling the p-square, determine the genotype of the offspring. Then summarize results.
Which of the following is an example of a positive feedback loop:
I. As the Earth’s surface warms due to global warming, water evaporation from a lake will initially increase. As the lake level drops, the surface area decreases and evaporation also decreases.
II. Water vapor from ocean evaporation creates low altitude clouds. Sunlight that would normally warm the Earth’s surface is instead reflected back to outerspace.
III. Water vapor from ocean evaporation creates high altitude clounds. Heat that would typically escape the atmosphere into outer space is trapped in the atmosphere instead.

MASTERY CONNECT MITOSIS
Answer:
According to the cell cycle data provided in the table, these data indicate that cells spend most of their time preparing for the cell cycle (third option).
Explanation:
The cell cycle is divided into two major phases, interphase —without cell division— and cell division or mitosis. Interphase in turn is divided into three phases prior to the division process:
G1 phaseS phaseG2 phaseAssuming that the complete cell cycle lasts 24 hours, the cell will remain in interphase for 23 hours - preparing for the next division - investing only 1 hour in cell division or mitosis.
The data provided by the table indicate that, at a given time, there will be a greater number of cells in the interphase stages, indicating that cells spend most of their time preparing for the cell cycle.

A water body that flows on the surface of the earth is called a stream. The river is a larger water body compared to streams. Stream is shallow likened to river volume.
A stream that flows into two distinct rivers is part of two:
Option b. Tributary
This can be explained as:
A reservoir is a lake that reserves the water either created naturally or artificially.A stream that merges into the river is called tributary or affluent.A watershed is a drainage bay where the water from precipitation gets accumulated and drains to common river or water bodies.Therefore, a tributary is a stream that flows into two different rivers.
