Answer:
The correct answer is -Sponges lack true tissue but have morevariation in cell type than animas in oter phylum.
Explanation:
Sponges are belong under phylum porifera which have diverse form encrusting sheets to volcano shaped mounds.
The tubes that contain in their body are differ in size from millimeter upto one meter.
The poriferans contain canal system and with help of this, they pump water which enters through a specialed pores called ostia that flows through canal called spongocoel and finally the water exits from their body through oscula.
The sponges show complex organization as their body contain single tube with 2 cell layer thick.
Ascon,leucon,sycons are the level of complexity.
The process of physical change in state, that occurs when water vapor or gas converts into a liquid is condensation. According to the kinetic molecular theory, the particles lose kinetic energy and slow down and thus become more arranged and have a definite shape but an indefinite volume, a liquid.
Answer:
4780.3 cm^3
Explanation:
A cone is a three-dimensional shape and its volume can be calculated using the formula:
V = 1/3 πr^2h or πr^2h / 3
Where V= Volume of cone (cm^3)
r= radius (cm)
h= height (cm)
π= constant (22/7)
In this question, the values of r and h are 13cm and 27cm respectively.
Hence, to calculate the volume of the cone, we say;
V = 1/3 × 22/7 × 13 × 13 × 27
V = 100,386 / 21
V = 4780.2857142857
4780.285 to the nearest tenth is ~ 4780.3
Therefore, 4780.3cm^3 is the volume of the cone.
Answer: (Algae & Grass) ---> Mouse ---> Wolf
Explanation:
- Two arrows pointing towards mouse means it feeds on both algae and grass. Hence, mouse can be called an herbivore (feed on plants only)
- A single arrow pointing towards wolf means it feeds on mouse only. Hence, wolf can be called a carnivore (feed on animal flesh only)
Thus, the relationships is best represented as (Algae & Grass) ---> Mouse ---> Wolf
OPTIONS:
-The fitness of offspring raised by one parent is high.
-Acquiring additional mates is relatively easy.
-Females give birth to multiple infants at once.
-Females are widely separated in an environment
Answer:
-The fitness of offspring raised by one parent is high.
-Acquiring additional mates is relatively easy.
Explanation:
When the fitness of offspring raised by one parent is high, that is if the survival and fitness of an offspring is largely favored when cared for by one parent, this might result to unequal parental investment being favored, since the survival of the offspring is mostly determined by one of the parents. For example, if breast milk and warmth of a female animal is very paramount or the survival of an offspring, there is likely going to be an unequal parental investment, since most of the caring would come from the female.
Unequal parental investment can also be favored when having access to additional mates is relatively easy.For example, if a male animal species is surrounded by many females of the same species, mating with multiple mates become easy, and when this occurs, it is very unlikely that the male would contribute anything to raising any offspring of any particular female mate, as he would just simply find it easy to move along with another female.
