The feeding relationship that exists between a tick and a cow is?
parasitism
mechanism
saprophytism
commensalism
The correct answer is Option A
Despite having hairy hides, ticks prefer to attack on cattle herds, and cows are not immune to them. Ticks spend their entire lives on animals of different types, including cows, feeding off the blood of their hosts. Even cows can contract highly dangerous infections from tick bites.
The most important parasite of livestock worldwide is the cattle tick.

The components of blood in man are?
red blood cells, white blood cells, plasma and water
red blood cells, white blood cells, and plasma
red blood cells, white blood cells, and platelets
red blood cells, white blood cells, plasma and platelets
The correct answer is Option D
Plasma, red blood cells, white blood cells, and platelets make up the four main components of a man.
Transporting oxygen and nutrients to the lungs and other tissues is just one of the many functions blood does.
The development of big muscles by a wrestler is an example of?
acquired characteristics
inherited characteristics
mutation
atrophication

Lack of nucleus is a feature in?
osteocyte
neurone
erythrocyte
leucocyte
The correct answer is Option C
Microscopic flat disk or doughnut-shaped red blood cells with a round indentation at the center, are not hollow.
Unlike white blood cells, red blood cells don't have a nucleus, which makes it easier for them to switch shape and travel throughout your body.
A universal recipient of blood belongs to blood group?
O
AB
B
A
The correct answer is Option B
People with type O- (O negative) red blood cells, known as universal donors, can donate their red blood cells to individuals of any other blood type.
Type AB-positive blood is referred to as the "universal recipient" blood type, as people with this blood type can receive blood from donors of any type.
The internal structure of a leaf that has larger air space is?
The spongy mesophyll's function is to allow for the interchange of gases (CO 2) that are needed for photosynthesis.
An example of arboreal animal is?
squirrels
duck
pig
rat
The correct answer is Option A
1. Koalas 2. Black spider monkeys 3. Siamang Gibbons 4. Three-toed Sloths 5. Squirrels 6. Rough green snakes 7. Veiled Chameleons 8. Common brown lemurs

The movement of sugars from the leaf to other parts of plant is?
guttation
transpiration
transportation
translocation
The correct answer is Option D
Materials in plants move from the leaves to other parts of the plant through a process known as translocation.
During photosynthesis, the leaves produce these nutrients, which are then carried through a long series of connected cells called phloem, to various other parts of the plant.
