The hormone responsible for milk let down in female farm animals is
Detalles de la respuesta
The hormone responsible for milk let down in female farm animals is oxytocin. Oxytocin is produced by the pituitary gland and is released into the bloodstream when the animal is ready to nurse its young or be milked. When oxytocin is released, it stimulates the contraction of the muscles in the mammary glands, causing the milk to flow from the teat. This hormone plays a crucial role in the lactation process and is essential for providing nourishment to the young in many species of mammals, including cows, goats, and sheep. The release of oxytocin can also be triggered by the stimulation of the teats, such as when a calf or kid suckles or when a milker applies a milking machine to the teat, making it a key player in the dairy industry.

Which of the following is a friend of farmer
Detalles de la respuesta
A friend of a farmer is the earthworm. Earthworms are beneficial to farmers because they help to improve soil fertility. They do this by consuming organic matter in the soil and excreting it as nutrient-rich castings that can be absorbed by plants. Additionally, earthworms burrow through the soil, creating channels for air and water to flow, which can help to increase soil aeration and drainage. This leads to a healthier soil structure, which can result in better plant growth and higher crop yields. For these reasons, earthworms are often referred to as "nature's tillers" and are considered to be valuable allies for farmers.

In subsistence agriculture
Detalles de la respuesta
In subsistence agriculture, surplus produce is small and savings are not made. Subsistence agriculture is a type of agricultural system in which farmers grow food primarily for their own consumption and for the consumption of their families and communities. In subsistence agriculture, farmers typically have limited resources and technology, and the focus is on producing enough food to meet basic needs, rather than producing a surplus for sale or trade. As a result, the surplus produce from subsistence agriculture is typically small, and farmers do not have the resources or market access to make savings or investments. Instead, they focus on producing enough food to feed themselves and their families. Farm sizes in subsistence agriculture can vary, and may range from small plots of land to larger holdings. The main focus is on producing enough food to meet basic needs, rather than maximizing production and profits. So, the answer to the question is surplus produce is small and savings are not made.

Layer's ration contains more limestone than grower's ration because limestone
Detalles de la respuesta
Layer's ration contains more limestone than grower's ration because limestone supplies sufficient minerals to layers for shell formation. Layers are chickens that are specifically raised for egg production, while growers are chickens that are raised for meat production. The composition of the feed for these two types of chickens is different, with layer's ration containing more calcium in the form of limestone. Calcium is an essential mineral for the formation of eggshells, and it is important for layers to have a constant supply of calcium in their diet. The higher level of limestone in layer's ration helps to ensure that the layers have access to the calcium they need for strong and healthy eggshells. On the other hand, growers do not require as much calcium in their diet as layers, so their ration contains less limestone.

Detalles de la respuesta
Root-knot disease of tomato is caused by a type of parasitic nematode. Nematodes are microscopic, worm-like organisms that can infect the roots of plants. In the case of root-knot disease of tomato, the nematodes feed on the roots of the plant, causing knots or galls to form. This can result in reduced growth, reduced yields, and in severe cases, death of the plant. The nematodes can survive in the soil for long periods of time and they can infect a wide range of plants, including tomatoes, peppers, melons, and many others. To control root-knot disease, it is important to practice good crop rotation, avoid planting susceptible crops in infested soil, and use nematicides if necessary.
Pregunta 30 Informe
The effects of practicing crop rotation include the following except
Detalles de la respuesta
The option that does not describe the effect of practicing crop rotation is "adding humus to the soil." Crop rotation involves planting different crops in a specific sequence in a certain area over time. The purpose of this is to maintain and improve soil fertility, control soil erosion, and prevent the build-up of pests and diseases. By rotating crops, the soil is given a chance to rest and recover nutrients that were taken away by previous crops, leading to healthier soil and better crop growth. On the other hand, adding humus to the soil involves adding organic matter such as compost, leaves, or manure to the soil. This helps to improve soil structure, water retention, and nutrient availability. While adding humus to the soil can complement the effects of crop rotation, it is not a direct result of practicing crop rotation.
