What is the relationship between an individual named Pinus palustris and an individual named Pinus elliottii? (2 points)

Answers

Answer 1
Answer:

The two individuals which are having the name Pinus palustris and Pinus elliottii belong to the same genus but are different species as their second name is unique.

What is Binomial nomenclature?

Binomial nomenclature is a system of naming living organisms such as plantsand animals in which each of the species is given a name which consist of two terms of which the first name is the genus name and the second name is the species name itself.

All the living organisms have two names by which they are called, one is the common name and the other is scientific name. Here, the individuals which have the name Pinus palustris and Pinus elliottii belong to the same genus but are different species as their second name is different.

Answer 2
Answer:

Answer:

The Binomial nomenclature is the method by which the naming of the organism is done. Each and every organism is known by two names. One is the local name and other is global name which is used by all.

Explanation:

Explanation: The plants and animals are named according to the binomial nomenclature in which the first word of the name describes the genus of the organism and the second word represents the species of the organism.

Here, the individual having the name Pinus palustris and Pinus elliottii belong to the same same genus but different species as their first name is same.

Effect of nutrition on puberty in domestic livestock animals

Answers

Answer:

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.

Nutrition plays a significant role in the onset and progression of puberty in domestic livestock animals. Proper nutrition is essential for the development and maturation of reproductive organs and the hormonal balance required for puberty. Adequate energy, protein, vitamins, and minerals are necessary for optimal growth and reproductive development.

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.

 What is the DNA backbone made of?- a nitrogenous base and a sugar molecule    
  - nitrogenous bases, sugar, and phosphates   
  -  sugar and phosphates
  - a polymer of nitrogenous bases

Answers

DNA or deoxyribose nucleic acid is a genetic material, which transmits information from the parent cell to the offspring. It is present in the nucleus or found in the nucleoid.

The correct option is:

Option C. sugar and phosphates

DNA is made up of:

  • Nitrogenous bases such as adenine, cytosine, thymine, and guanine are involved in the specific pairing that provides the helical structure of DNA.

  • The DNA consists of a pentosesugar, known as deoxyribose.

  • The backbone of the DNA is made up of the phosphate group attached with sugar, which provides DNA with a negative charge.

Thus, the DNA backbone is made up of phosphate and pentose sugar.

Therefore, Option C is correct.

Cellular respiration involves a series of chemical reactions. Which of the following is a primary way that enzymes affect these reactions?A. They decrease the pH of the products.
B. They increase the rate of the reactions.
C. They take the place of oxygen as a reactant.
D. They change the location of the reactions in the cell.

Answers

Cellular respiration involves a series of chemical reactions. The enzymes increase the rate of the reactions. So option “B” is the correct option as far as the given question is concerned. The reactions that are catalysed by enzymes actually helps the organism to grow, respond to various changes in the environment, reproduce and continue maintaining their own structures. Cellular respiration is also considered a part of the metabolism process. This process actually helps in carrying the oxygen through the blood.

Use the words haploid cell, diploid cell, and fertilization all together in a sentence.

Answers

Using the wordshaploid cell, diploid cell, and fertilization all together in a sentence -  Fertilization is the union of two unicellular, haploid gametes to produce one unicellular, diploid zygote.

The process of combining the male gamete, or sperm, with the female gamete, or ovum. The product of fertilization is a cell called a zygote.

  • Fertilization takes place when two haploid cells fuse together such as sperm cells and egg cells.
  • Haploid cells have a single set of chromosomes.
  • The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes that fuse during fertilization.
  • Diploid cells are a cell that containstwo sets of chromosomes that are formed after fertilization also called a zygote.

Thus, the correct sentence would be - Fertilization is the union of two unicellular, haploid gametes to produce one unicellular, diploid zygote.

Answer:

The sexual life cycles involve the alternation between meiosis and fertilization. Meiosis is a process where the diploid cells gives a rise to haploid cells, and fertilization is the process where two haploid cells (gametes) fuse to form a diploid zygote.
