there mammals so they need to have sexual reproduction compared to fish they dont need sexual reproductions to have a organism (baby)
Explanation:
Yes, the animals like wolves and lions reproduce by se-xual reproduction.
Se-xual reproduction in mammals:The process of production of offspring by combining genetic components from two individuals of different se-xes, that is, male and female is termed se-xual reproduction. In higher animals like mammals, that is, lions and wolves, the process of se-xual reproduction takes place.
The mammals generate gametes, that is, egg and sperm via the process of meiosis in gonads, that is, ovaries in females and testes in males. The production of eggs takes place by the process of oo-genesis, and the production of sperm takes place by sperma-togenesis.
Afterwards the fusion of male and female gametes takes place, that is, the process of fertilization occurs and generate a diploid zygote.
Thus, the given statement is true.

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.
A stream that flows into two different rivers is part of two
A reservoirs.
B. tributaries.
C. divides.
D.
watersheds.
Answer:
Tributaries
Explanation:
I wound think that they would be branching of so thats what i would say
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.

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.
Identify landform B, explain how it forms, and tell whether it is the result of erosion or deposition.

You are studying the genomes of deep sea organisms when you come across a brand new species of lantern fish. In the lab, you measure the percent of nucleotides in the nucleus that contain adenine as their base and that percent is 30%. 10. Calculate the percent of thymine nucleotides: _______________ 11. Calculate the percent of guanine nucleotides: _______________ 12. Calculate the percent of cytosine nucleotides: _______________
Answer:
Thymine = 30%
Guanine = 20%
Cytosine = 20%
Explanation:
DNA is a double-stranded molecule made up of long chains of nucleotides (A, T, G, C). Each chain is the strand. However, According to Chargaff, the amount of adenine in a DNA is equal to the amount of thymine while the amount of guanine equals the amount of cytosine. That is:
(A = T) + (G = C) = 100%
All together, they all make up 100%. According to this question, the percent of nucleotides in the nucleus was measured to contain adenine as their base which is 30%.
If Adenine is 30%,. Then Thymine is 30% as well.
A = T = 30+30 = 60%
Hence,
60% + G + C = 100%.
G + C = 100 - 60
G + C = 40%
Since, G = C, 40/2 = 20%. Hence, G = 20% while C = 20%
All together,
A = 30%
T = 30%
G = 20%
C = 20%

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.
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.
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.

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.

How do cold ocean currents affect climate ?
A molding machine in a factory was not working very well. About a third of the time, the plastic squirt guns that it was making come out with a flaw in the handle. The repair mechanic adjusted the stamping pressure. Then she ran one gun through. It came out just fine, so she figured she had solved the problem. What was/were the error(s) in the conclusion of the repair mechanic?
a. Not enough subjects
b. Subjects were not similar
c. Conditions were not kept the same
d. The experiment was not reproduced
Answer:
a. Not enough subjects
Explanation:
In the context, it is given that in a factory, a molding machine is not working properly. The molding machine produces a gun made of plastic. But the machine was produces a defective piece about a third of he time it produces the gun.
The mechanic adjusted and repaired the stamping pressure and ran only one gun through which came out to be fine. But there was an error in the conclusion of the repair mechanic as she did run the machine only one time. She did not have enough subjects and should have run many times to see if the error still exists, as the machine showed error only about a third of the time during the process.
Thus the error in the experiment includes the lack of the enough of the subjects. We cannot come to the conclusion only with one time success.

main stages of the cell cycle
Answer: The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
