b. chordates
d. vertebrates
Answers
Answer:
invertebrates
Explanation:
The invertebrates lack a backbone. They include molluscs, annelida, arthropods and protozoa. They have a segmented body and well developed digestive system. Some are mostly found in sea, land or deserts. Some invertebrates lack a rigid exoskeleton. Some are pseudocoelum, possessing cavity between body wall. Some invertebrates have an incomplete digestive system consists of a digestive cavity with one opening which serves as both mouth and anus. Some invertebrates have a complex nervous system consisting of brain and several other sense organs.

The answer is FALSE. Convection currents do not produce the heat in the earth’s interior. They are rather responsible for distribution of this heat in the mantle. The radioactivity of the earth's core is the main source of heat. As the materials such as uranium decay, they release heat that keeps the interior hot.
Final answer:
Convection currents do not produce heat in the Earth's interior, but rather they transfer the heat generated mainly by radioactive decay.
Explanation:
Convection currents do not produce heat; instead, they aid in the transfer of thermal energy from one place to another. In the Earth's interior, the heat is generated primarily through radioactive decay, and this heat is then moved towards the surface of the Earth by convection currents. By analogy, consider a pot of water being heated on a stove. The stove (analogous to radioactive decay) generates the heat, and the water circulates that heat through convection currents, with warmer water rising and cooler water sinking.

b=Blue recessive
Possible Geno and Phenotypes
BB=Brown eyes
Bb= Brown eyes
bb= Blue eyes
Final answer:
In genetics, dominant alleles are often represented by capital letters and recessive alleles by lower-case letters. Therefore, the allele for brown eyes can be symbolized as 'B' and the allele for blue eyes as 'b'.
Explanation:
In genetics, capital letters are used to represent dominant alleles, while lower-case letters are used to represent recessive alleles. Therefore, we can use 'B' as the symbol for the dominant brown eye allele and 'b' for the recessive blue eye allele. When both 'B' alleles are present (BB), or when a 'B' and a 'b' allele are present (Bb), the individual will have brown eyes, because 'B' is dominant. However, when both 'b' alleles are present (bb), the individual will have blue eyes, because the blue eye allele can only be expressed when the dominant allele is not present.

If the 2° consumers have 467 kcal, how much energy did the producers have?
Thank you to any answers!
Answers
a) 23.4 Kcal is the energy will the 3° consumers receive.
b) 46700 Kcal is the energy producers have.
Explanation:
The energy value is given for the trophic levels. There is a 10 % rule of energy transfer which is applicable to the producers and consumers in the energy pyramid. According to it 10 % energy is transmitted to upper level in a pyramid while 90% gets dissipated in the form of heat.
Energy of producer = 23400 kCal
energy transferred to tertiary consumer = ?
At first the energy transferred to primary consumer is calculated as:
10 % of 23400 Kcal
x 23400
energy transferred to primary consumer = 2340 Kcal
energy transferred to secondary consumer:
10% of primary consumer energy
x 2340
= 234 Kcal
energy transferred to tertiary consumer:
10% of energy of secondary consumer
x 234
= 23.4 Kcal
Tertiary consumer will recieve 234 Kcal of energy.
b) Energy of secondary consumer is 467 Kcal
energy of producers =?
energy of producer was 100 times the energy of secondary consumer
467 x 100
= 46700 Kcal.
