i need help with this,
it’s for biology

Answer:

B

Explanation:

Explanation:

for sin we divide the opposite by the hypotenuse

and for cos we require the adjacent divided by hypotenuse

we can get it through

a²+ b²=c²

ur unknown in this case is the adjustment which you can either substitute with a or b

a² + 3²=5²

a²=5²-3²

a²= 25-9

a²= 16

[tex] \sqrt{a ^{2} } = \sqrt{16} [/tex]

a=4

so that now we have found that I just sent we can find the cos of A

cos A= ⅘

Answer:

Reproduction is the process of producing offspring, whereas heredity is the process

of passing on traits.

Explanation:

PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!

Reproduction generally means making copy of something, like giving birth/breeding, duplicating.

Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!

They definitely aren’t same!

Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.

Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.

Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.

Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.

Answer:

I think its the third one should be

Answer:

The graph above shows that the position of the body is changing with time exponentially and it is accelerating. The velocity of the body is changing with time and as a result the distance it is covering per time will be changing. Generally the graph of positions against time for a body that is accelerating will always look like the diagram above. For constant velocity motion, the graph will be a straight line with slope equal to the velocity of the body.

Explanation:

The velocity - time graph will for a undergoing the motion described by this graphics will be a straight line graph with it slope equal to the acceleration of the body.

Answer:

D. Center of gravity.

Explanation:

Gravity always acts downward on every object on earth. Gravity multiplied by the object's mass produces a force called weight. Although the force of an object's weight acts downward on every particle of the object, it is usually considered to act as a single force through its balance point, or center of gravity.

Answer:

1. Whilst flood events are devastating to humans they are a natural occurrence that can provide negative and positive important environmental impacts.

Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils. They also replenish water resources and trigger life processes such as bird breeding events, migration, and seed dispersal in flora and fauna adapted to these cycles, while good soil moisture can allow crops and pastures to be established.

Explanation:

Cones attract animals that will help with plant reproduction. (no, because no animals are attracted to pine cones)

Cones are used to as food source for the plant. ( no because food is not stored in it, the seeds are, plants don't eat their own seeds)

The cones catch rainwater for the tree to use. (no! which tree is going to suck water from their cones?)

Answer:

Independent variable: Type of battery

Dependent variable: Time the clock stopped

Control: None for this experiment

Constants: Same type of clock

Explanation:

Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.

Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY

Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.

Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.

Answer:

Independent variable: Type of battery

Dependent variable: Time the clock stopped

Control: None for this experiment

Constants: Same type of clock
