The large size of the musk ox _______. a. helps minimize heat loss b. is offset by its long legs c. helps the animal graze less often d. helps maximize heat loss
A. Helps minimize heat loss
The musk ox is found in cold climatic regions. Its larger body size imparts it a smaller surface area relative to its volume. The lesser surface area, relative to its large volume, exposed to the surroundings helps the organism to lose less heat. Hence, a smaller surface area to volume ratio of musk ox, as contributed by its larger body size, help it to stay warm in cold climates.

A biologist is writing a report about a group of rattlesnakes that all live in the state of Florida. All rattlesnakes in this group can breed with one another and produce offspring that can reproduce together. The report includes statistics about the number of these rattlesnakes, their breeding rate, and the ranges of their sizes and other traits. In this report, the biologist is describing? A.a community in Florida. B.a biome in Florida. C.a population in Florida. D.an organism in Florida.
The correct answer is option C, a population in Florida
The population description is an efficient language is termed as demographics. The descriptive components of the demographics are –
a) Population Size – It gives the number of individuals within a population
b) Population Density – It defines the size of a population with respect to the space occupied by it
c) Age Structure of the Population – It categorizes different individuals in a population group to different age sections
d) Fecundity – It describes about an individual that is able to produce during a given period of time
e) Morality – It gives the death and birth rate of a population
f) Sex ratio
All of the following lists include sources of point-source pollution EXCEPT : A) oil spills , irrigation , fertilizers , pesticides B) pesticides , oil spills , irrigation , leaky underground storage tanks C) drainage from industrial plants , oil spills , runoff from street gutters , chemical spills D) pesticides , herbicides , animal waste , irrigation
What is likely to happen in the long term if the Earth continues to absorb more energy than it emits? a. The Earth will discontinue recycling energy. b. Organisms will begin to compensate for the change by incorporating more energy. c. The overall temperature of the Earth will increase. d. The nutrient cycles will happen more frequently.
Positive feedback mechanism is the one by which the changes leads to more changes of same type.
During child birth, the head of the baby is pressed against the cervix which in turn send the nerve impulses to brain. Brain makes the pituitary gland to secrete the hormone oxytocin. Oxytocin is released in blood and causes the uterine contraction. As labor continues, more stimulation of cervix and intense uterine contractions lead to more release of oxytocin.
I believe the correct answer is "C.) opposite"
The correct answer is Oxygen
b. sedimentary rock
c. igneous rock
Sedimentary and igneous rocks may display two different pore size. According to a rough estimate the grain size of Sedimentary rocks is 5mm and grain size of igneous rock is 2mm.
The Gaia hypothesis is an example of negative feedback.
Negative feedback is seen in Gaia hypothesis. This hypothesis is a theory given by James Lovelock stating that organisms interact with their inorganic environment to establish a complex system that will enable them to maintain and survive on the planet. Gaia hypothesis is a theory which is given by James Lovelock. This theory posits that the organic and inorganic components of earth evolved as a self-regulating system or a single living.
In the negative feedback mechanism, there is a negative correlation in between the process rate and the concentration. They control the process rate to prevent substance accumulation. Majorly negative feedback is involved to maintain the homeostasis in the environment. They help in achieving equilibrium state by going back to the normal state.
According to this theory, the living system on the planet automatically controlled atmospheric content, global temperature, ocean salinity, and other factors also which maintain their own habitability. This entity has controlled the self-regulatory negative feedback that helps in keeping the planet conditions within boundaries that are more favorable to an individual’s life.

Which of the following best describes the solar radiation absorbed by and radiated from earth? a. Most incoming solar energy is absorbed by the atmosphere. b. Only a small fraction of energy radiating from Earth is from the atmosphere. c. The Earth’s surface is responsible for a small fraction of heat radiation to space. d. Earth’s surface absorbs little of the energy that strikes as solar radiation.
Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.
In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.
the answer is C. i took the quiz
So, option A is your answer!
Hope this helps!
Biology help please i will upvote Matching A. Interphase B. Prophase C. Metaphase D. Anaphase E. Telophase F. Cytokinesis _____1. Chromosomes line up at the equator and spindle fibers attach to the centromeres of the chromosomes. _____2. Division of the cell cytoplasm once mitosis is complete _____3. Before cytokinesis, 2 nuclear envelopes form around each set of chromosomes. _____4. Before Mitosis begins, the cell prepares for division by increasing in size and duplicating the DNA. _____5. Sister chromatids are separated by spindle fibers and the 2 sets of identical chromosomes are pulled to opposite ends of the cell _____6. Chromosomes condense the nuclear membrane breaks apart and spindle fibers form.
if not ik some of them
The correct answer is option (b). yellow and orange.
The carotene or tetraterpenoids is a class of pigment produced by many organism including plants and the fungi. This pigment gives the yellow and the orange color to the leaves.
Generally, the leaves are green colored, due to the presence of chlorophyll, but during the fall, the amount of chlorophyll is decreased and the carotene gives a orange or yellow color to the leaves.
The responsible management (use and conservation) of the earth's resources indefinitely using science-driven policies and practices is called ________.an environmental conservation trustthe maximum sustainable yieldsustainable developmentlandscape ecology
Unlike rocks, all minerals ________ and ________. A are expensive, are difficult to get B occur naturally, have a fixed chemical composition C contain metal, dissolve in acid D fracture, contain silica
The correct answer is B!
Why is this?
A mineral is a naturally occurring, inorganic solid with a definite crystalline structure and chemical composition. All minerals contain one or more elements, which are pure substances that cannot be broken down into simpler substances by chemical means.
