Hi!
- Epithelial cells (I believe)
- Nervous System
- Skeletal System
Explanation:
- Epithelial tissue helps cover your "exterior sources". Therefore I'm pretty sure the first one is Epithelial cells.
- The Nervous System has to do with sense of feeling or sense of touch mostly. The Nervous System controls everything you do! ex. touching a table uses the nervous system.
- The Skeletal System helps your body move and supports a lot of different things in your body. All of those other options are not correct just because they do not support. Here is what I mean in the shortest way possible:
- Circulatory- has to do with your lungs
- Lymphatic- involves a network of vessels
- Excretory- elimination of waste
Therefore these are your answers #1, #2, and #3.
Hope this helps!

Answer:
The correct answer is - ice is less dense than liquid water.
Explanation:
In most of the liquid when they get freeze their molecules come closer to each other, however, in the case of the water the molecules come closer to form a crystalline lattice structure with low energy.
But when it forms crystal the water molecules are pushed apart farther as they have hydrogen bond in them. It causes the property of denser water than ice.
Thus, the correct answer is - ice is less dense than water.
this is because the particles are further apart (due to hydrogen bonding), so in the same volume there are LESS particles in ice than there is in the same volume of water.

a(n) = a r^(n-1)
a = first term = 3
r = common ratio = 0.6
n = number of terms = 10
substituting the values:
a(n) = 3 * (0.6)^(10-1)
a(n) = 3 * (0.6)^9
a(10) = 0.030
Sum of the ten terms = 3 (1-0.6^10)/1-0.6
= 2.98/0.4
= 7.45
Answer:
7.45

Explanation:
Nutrition is a major component determining puberty in domestic livestock animals. Adequate and balanced diet is needed for appropriate growth, development, and the attainment of reproductive maturity. The effects of diet on puberty are varied. Timely puberty onset relies on optimal body weight and size obtained by suitable diet. Nutritional shortages or imbalances can delay puberty by altering hormonal control. Nutrients including proteins, vitamins, and minerals are important for hormone production and activity. Insufficient nutrition might impede the development of reproductive organs and postpone sexual maturation. Furthermore, undernutrition can lead to irregular estrous cycles, lower conception rates, and extended anestrus, reducing fertility. Proper diet also effects stress response and intestinal health, thereby altering hormonal balance and puberty. Achieving adequate nutrition according to specific requirements is crucial for guaranteeing prompt puberty and increasing reproductive performance in domestic livestock animals.

Insufficient nutrition can delay puberty and result in delayed or irregular estrus cycles in female animals. In males, poor nutrition can lead to delayed testicular development and reduced sperm production. On the other hand, excessive nutrition, especially high energy diets, can also have negative effects on puberty. Overfeeding can lead to excessive fat deposition, which can disrupt hormonal balance and delay puberty.
Balanced nutrition, tailored to the specific needs of each species and breed, is crucial for promoting timely and healthy puberty in domestic livestock animals. Proper nutrition ensures optimal growth, development, and reproductive performance, contributing to overall herd or flock productivity.
